My Little Pony: Friendship Is Magic/WMG/Confirmed

These guesses turned out to be true. If you have a guess about something else, then

"Meta Guesses go here

Setting Guesses go here

Mane Character Guesses go here

BUT Pinkie Pie Guesses go here

Secondary Character Guesses go here

Royalty Guesses go here

Minor Character Guesses go here

Future Stories go here

Jossed Guesses go here"

"and you can still go back to the Main WMG Page, here"

The Grand Galloping Gala is going to play a larger role in the storyline than everybody thinks.
At first, we all thought it was just a story element in "The Ticket Master" that was over and done with at the end of the episode. But then comes "Suited For Success", where it focuses on Rarity making dresses for the Gala. It then lends credence to the idea that the Grand Galloping Gala is going to play a HUGE part in the story, possibly as near or in the Season Finale.
 * Lauren Faust has stated that she wanted to incorporate an overarching storyline, but couldn't due to Executive Meddling. Plus, if you look closely, there's Anachronic Order in place. It isn't too far of a stretch to think that this is her attempt at Getting Crap Past the Radar (so to speak).
 * Yup, it's the season finale.

Earth ponies bless the land.
Word of God (via Lauren Faust's Deviant ART account) says that earth ponies are not the have-nots of the world, but rather have greater strength and endurance than the other types; and moreover they have a strong connection to the land and its plants and animals in the same way that pegasi have a strong connection to the sky and weather. (Fluttershy is an odd duck pegasus for getting along with animals so well.) So the guess is that earth ponies sort of 'bless' the land they're working, just by being there. A farm run by earth ponies will generate more and better crops than the same land run by unicorns. This could also explain the tradition of not using magic in the Winter Wrap-Up -- by putting in the hard work to bring in spring by hand hoof, they make the whole area more fertile for the rest of the year.
 * For that matter, given that natural processes such as weather (or the sun rising) simply do not occur without the ponies' intervention, one has to question whether a unicorn would even be capable of getting plants to grow at all.
 * Presumably a unicorn or pegasus could grow flowerbeds and small gardens if they live in the vicinity of earth ponies.
 * Apparently confirmed by Word of God
 * The sub-theory that unicorns and pegasi can't grow anything is pretty much confirmed in Hearth's Warming Eve. Pre-Equestrian Unicorns and Pegasi disliked Earth Ponies, but were dependent on them for food. This must mean that only Earth Ponies are capable of growing food at all. Without them, there would be no crops, and Equestria would starve. This is further hinted at by the fact that many Earth ponies have food-based names (the Cake family, the Apple family, Pinkie Pie, Golden Harvest, etc.)
 * The sub-theory wasn't confirmed. The other tribes didn't care for earth ponies, but their attitudes made it clear that they would rather somepony else grow their food than do it themselves . Their poor opinion of the earth ponies seem to revolve more around their lack of impressive flashy abilities, and the unicorns and pegasi also hated each other, so they were hardly being singled out. The episode actually kind of implied the opposite, because the territory that became Equestria had plants and weather without earth ponies or pegasi. Unless pegasi and unicorns have some magic attribute that prevents plant growth around them, which seems unlikely, they should be able to grow plants as well as anyone without magical cultivation powers.

Princess Cadence and/or Shining Armor (featured on a display seen during a party at Hasbro's world headquarters) will appear in the show.

 * Confirmed!

"The Best Night Ever" will be Meta
Episode plot will be about the disappointment of Mane Cast because the GGG will be different than they excepted. That'll probably be the future fan reaction to that episode.
 * Confirmed, effectively. All the trouble in the episode was about the girls trying to force their high expectations of the Gala onto the rather dull reality, with predictable (and amusing) results. And sure enough, there's a lot of fans complaining the episode didn't meet their expectations.

"The Return Of Harmony Part 2" will start with Twilight being Alone in a Crowd
Discord's unleashing chaos on Equestria will do what happened to the Mane Cast to everyone, leaving Twilight, possibly out of Cruel Mercy, all alone with everyone she knows and cares about a twisted inversion of their true selves, even Spike. This would likely be one of the biggest Tear Jerkers imaginable but also lead to an epic Back From the Brink moment.
 * This did happen sadly.

The elements were never in the maze
Twilight Sparkle and Celestia both focused on the "twists and turns" part of Discords riddle. However, that makes "Back where you began" meaningless, as none of them had set foot in maze before, and it holds no signifigance to any of them. But where had they set foot? The place where they managed to recover the elements of Harmony, and the place where their friendship began - the castle in the Evergreen forest.

When Discord tried to obtain the elements of harmony, the Elements couldn't survive contact with the very embodiment of chaos. They shattered again, and their essence returned to their resting place - exactly where everything began.
 * Also, Fridge Brilliance. The twists and turns are my master plan part makes sense when you realize he wanted them to go into the maze, which was his master plan.
 * this new sneak preview clip
 * Confirmed.

In the season 2 premier the elements of harmony will be striped from the six
Causing them to find the secondary elements they represent
 * Applejack: Loyalty- In Applebuck Season Applejack was so overly loyal it hurt her
 * Fluttershy: Generosity- In Green Isnt Your Color It was Fluttershy's loyalty to her friends specifically Rarity that had her modeling
 * Pinkie Pie: Loyalty- FOREVER
 * Rarity: Magic- As the only other unicorn she has to be
 * Rainbow Dash: Laughter- As seen in Fall Weather Friends she's a massive prankster
 * Twilight Sparkle: Honesty- The girl has trouble keeping secrets
 * Doubtful on ALL of these, for the following reasons:
 * Twilight's special talent, what earned her a cutie mark, what's she destined to do her ENTIRE LIFE, is magic. She knows more about it than anypony and is one of the few ponies that can do all types of magic. Rarity's magic skills are nowhere near Twlight's. There's no element, not even honesty, that fits her better.
 * Rarity may be a little snobby, but she really is the most generous pony in the mane cast. She worked hard making beautiful dresses for all her friends at no cost, she insisted on helping out Twilight with her bad hair/mane day in the first episode, she gave that dragon her tail for his mustache (without being sure if it will go back) and she constantly thinks of others. Fluttershy is nice but she hasn't exhibited the level of generosity Rarity has.
 * I can see Applejack as loyalty, but she's also the most honest pony there. No other pony fits honesty the way she does. (note that the few times she does lie to another pony, she's VERY bad about it)
 * She was bad at lying even after Discord corrupted her! Honestly, if having an obvious tic after being Mind Raped into being a pathological liar doesn't at least imply that she's best suited, nothing does!
 * Like Twilight, Pinkie's element also fits her cutie mark. She's all about making people laugh and smile, not even Rainbow Dash can top her in fun and laughter.
 * Partiality Confirmed, Discord did strip 5 of the girls elements and trick the 6th into leaving

Season Two will showcase a Halloween Episode. (CONFIRMED, though referred to as "Nightmare Night")
Depending on how aware the production crew is of fanfiction, it might bear resemblance to Story of the Blanks. "But I wanted to be a Zombie next year!"
 * Although it may end up marginally lighter, but scary nonetheless. Either that, or it will rely on Defanged Horrors.
 * I can totally see this happening now. For various reasons, the mane cast and the CMC all decide to take part in a stage show on Halloween. The plot of the play either closely resembles, or is, the plot of The Story of the Blanks. That way, they could make it as creepy as the game without upsetting the censors. I would totally write a fanfic on this if I was any good at writing fanfictions. In fact, I may do so anyway.
 * "And then, Applejack was a zombie."
 * Well, they didn't seem to. However there IS mention of zombies.

Before the end of Season 2, Princess Luna will do a Triumphant Call Back of Nightmare Moon's surprise appearance

 * This time, the Mayor introduces Princess Luna to the crowd (they are apprehensive but polite).
 * On stage a cloud of swirling mist appears, then a clap of thunder and lightning....
 * But instead of the Evil Laugh, there will be a gleeful, happy giggle....
 * Ta-dah! It's Luna, and she gives an altered version of her previous speech (avoiding the Ironic Echo by not quoting it exactly).
 * The crowd, which remembers the last time she popped up in this manner, exhale a relieved sigh.
 * Princess Celestia is at the back of the audience, applauding (she loves a good entrance).
 * Confirmed! NOW THE FUN HAS BEEN DOUBLED!!!

"Luna Eclipsed" includes at least one costume based on a character from a later episode.
Most likely a monster and/or villain.
 * Spike's could count.
 * Star Swirl the Bearded got referenced in a later episode, though that might've been more of a Call Back.
 * A little filly mentioned wanting to be a zombie next year. You don't think...?
 * Confirmed. Turns out Berry Punch's costume was Daring Do.

There will be episodes where Twilight is not present.
Now that the other mane characters (possibly Spike included) have been given permission to write friendship reports to the Princess without Twilight's involvement, there's no longer a requirement for Twilight to appear in a given episode.
 * I was correct, she didn't appear in Sisterhooves Social.

The first episode of Season 2 will be a Wham! Episode.
This theory relies on Season 2 being more like the original idea Lauren Faust had. Most likely it would take place in Canterlot, shortly after the events of "Best Night Ever", with a new villain (Maybe even a Knight of Cerebus ) attacking.
 * Does Discord's cutie-breaking and mind-raping count as at least partially confirmed for this one?
 * I'd say it does.
 * Of course, if you consider that "Return to Harmony" was originally scheduled as Season 1 episodes, and that "Lesson Zero" is the true first episode of Season 2... well, this is still pretty much spot on.

Zecora will appear in "The Cutie Pox".
Zecora is the one they go to when they need to deal with an unusual disease or some other weird phenomena. It seems appropriate that she could offer help with Apple Bloom's cutie pox.
 * Confirmed. A trip to Zecora's was what started the mess, and Zecora's help is what ended it.

Season 2 image guesses.
Jayson Thiessen tweeted these two teasers of Season 2. They're not much, but the time for crazy speculation is NOW!
 * Twilight is still a bookworm, Spike is still her #1 assistant (Confirmed).
 * The images are from the first episode, and for whatever reason Twilight is reading up on the Elements of Harmony again (Jossed).
 * They're most likely from the sixth episode, since their filenames start with "MLP206" (Confirmed).
 * It is indeed from episode 6, "The Cutie Pox". The second image is the part where Spike finds the "Perplexing Pony Plagues" book while the first is the part where Twilight begins to explain the symptoms of Cutie Pox.

"The Cutie Pox" will end with all the marks disappearing...
...except for on her flank. Apple Bloom will initially be dismayed and think she's still sick, but after a moment will realize that she discovered her talent earlier in this outing.
 * Partially confirmed, but unfortunately, none remained.

"Sweet and Elite" will have a Sweet and Sour Grapes ending.
Where Rarity chooses her friends, but still manages to forward her business in some fashion.
 * Combined with the above theory, perhaps she puts Diamond Tiara in her place, and the relative is actually impressed with how she handles her.
 * Confirmed, just not the part about Diamond Tiara.

There will be an episode featuring the Friendship Express Train.
It has its own toy, it was added to the opening, Shout Factory's upcoming DVD The Friendship Express is named after it & features it on its cover, and train tracks & tunnels are seen at the end of "Sweet and Elite".
 * Possibly confirmed.
 * Confirmed to be "Hearth's Warming Eve".
 * "The Last Roundup" even more so.
 * And now "MMMystery on the Friendship Express" is a whole episode taking place on the train.

The play during "Hearth's Warming Eve" will be a framing device for a flashback
Perhaps Twilight discovers the true history of Equestria while doing research for the play, or Celestia decides to tell the story to the mane cast, due to the play being dramatized and therefore not entirely accurate.
 * Confirmed as of the preview clip provided. The play itself serves as the vehicle for the flashback, however.

In "Hearth's Warming Eve", the play itself will be...

 * Not unlike the story of the Pilgrims landing at Plymouth's Rock (but with horse-related puns)
 * Not unlike the story of King Arthur, and his founding of England
 * Something involving the Princesses founding Equestria
 * Mythopoeia
 * Similar to the story of one of the G1 movies (most likely, The Movie)
 * Something completely different
 * The same story from the iOS game Twilight Sparkle: Teacher for a Day (the beginning of which can be glimpsed here)
 * Appears to be true, judging by the new synopsis.
 * Now almost certainly true, judging by a preview clip.
 * Pinkie pie's cutie mark story. somehow.
 * Show the battle between the Princesses and Discord, since Discord ruled Equestria before them.
 * The literal founding of Equestria the country, not its creation.
 * Appears to be true, judging by the new synopsis.

"Hearth's Warming Eve" will be the Crowning Moment of Heartwarming to end all Crowning Moments Of Heartwarming.

 * Literally true, in the sense that the magic of friendship that defeats the Wendigos and thaws the land is represented by a heart-shaped fire, literally "heart warming". In the larger sense of the show, being able to maintain that heartwarming appears to be necessary to keep the Windigos at bay.

The train will be involved at some point
It's part of The Friendship Express episode pack, and other than the first two episodes, all the episodes involved the train somehow.
 * Actually, the one in "Over a Barrel" was a different train, making it even more likely that the train will play a big role in this episode.
 * It played a major role.

The eponymous "Super Speedy Cider Squeezy 6000" is a cider-making machine built by the Flim Flam brothers.
The contest will be a Pony Versus Machine challenge between the Flim Flam brothers' invention and the Apple family's old-fashioned cider-making ways.
 * If this is the case, this makes the Aesop of the day the merits of hard work and dedication over time-saving shortcuts that may backfire.
 * Alternatively, the contest ends in a draw: the Brother's machine malfunctions, but Applejack ends up too exhausted to make cider. The Aesop is two-sided: Don't be too stubborn to try new ways of doing things, but don't skimp on hard work just to make less effort. The letter to Celestia would be written by Applejack, with the Brothers providing a post-script.
 * This is correct, but anyone could come to that conclusion.

It well be a retelling of the John Henry story, but with ponies.
Except Applejack won't die at the end.....hopefully.
 * Kinda?

Part of the episode will depict the story/-ies that Rainbow Dash is reading in an animated form (like Granny Smith's tale from "Family Appreciation Day")
If only to make her finding them interesting more relatable to the audience.

There will be an aesop about not needing to rush into romance.
At this point in the series, most of the main cast don't have any obvious Love Interests. Rather than shoehorning in a bunch of new guys, the episode will address this by showing they're content without boyfriends, and don't need to rush out and find one in order to be happy. To drive this point home, one of the girls will try and quickly strike up a new relationship, but struggle with it until she realizes she was happier before. (For extra Aesop points, this could be one of the Cutie Mark Crusaders -- most likely Apple Bloom or Sweetie Belle -- after getting teased for being a 'lonely loser' by Diamond Tiara.)
 * While nothing of the sort happened as described in the guess, that could be what the episode was about.

Big Macintosh will play a role in "Hearts and Hooves".
Potentially getting a chance at a Relationship Upgrade with somebody. Not necessarily one of the main cast, though.
 * Confirmed! Big Mac and Cheerilee, courtesy of the CMC.

Hearts and Hooves will revolve around a Valentine's Day type holiday.
Equestria has several holidays that resemble real life ones, and this one airs a bit before Valentine's, so it's pretty likely.
 * Title Update (adding "Day") seems to prove this true.

The CMC misunderstood either or both Big Mac and Cheerilee when they set off to try to pair them up for the holiday...
More than likely, Cheerilee will be discussing the background of Hearts & Hooves Day to the class, mentioning that she's got no one special for that day herself, prompting the CMC to take action to pair her with the most available bachelor they know, Apple Bloom's brother Big Mac. Hilarity Ensues.
 * Alternate theory: Cheerilee and Big Mac have known each other for some time but have been platonic friends. They decide to "play along" with the fillies' scheme only to discover that there is some attraction there after all.
 * The first guess was correct.

Zecora will show up in this episode. (A Friend In Deed)
After all, she was in a similar situation in season one where all the other ponies avoided her for reasons she couldn't figure out. Perhaps Pinkie Pie will go to her and ask how she dealt with it.
 * Zecora does indeed show up, but she's just passing through as a cameo and has no relevance to the plot.

Pinkie Pie's leaked "Smile" song will be in this episode. (A Friend In Deed)
Based on the synopsis alone, and the message behind the song itself, this is very likely.

There will be an episode about Rainbow Dash breaking her wing.
And being forced to live without flight until it heals, or something like that.
 * Confirmed, there's an episode where she breaks her wings.

The warning will be incomplete.
Cut off before imparting some vital information. For instance, if it concerns one of her friends facing some horrible peril in the near future, she won't learn who, sending her desperately running all through Ponyville trying to figure it out before it's too late.

The message from the future is a metaphor for the episode summaries.
Upon receiving the message, Twilight will go overboard interpreting it in the worst possible ways, predicting doom and gloom based on a tiny scrap of information. Things may be bad, but not nearly as bad as she anticipates, leading to An Aesop about not leaping to conclusions. Much like how the fandom keeps reacting to a single sentence summarizing the basic plot by predicting the absolutely WORST. POSSIBLE. THINGS.

This will be another one of those really meta-Brony episodes.
The moral will be something along the lines of "Don't worry about the future". Bronies are always worried about future episodes and indeed the future of the show itself, so this would be some sound advice to them.

Future!Twilight's message was...
A preview clip is out! Some guesses as to what Future!Twilight was trying to say...

"Whatever you do, don't...
 * eat at the new Mexican restaurant opening on Tuesday! A chili pepper landed in my eye and gah it just went downhill from there!"
 * Let Pinkie out of your sight.... She has done... Horrible things. Horrible things. You Don't Want to Know."
 * eat the apple pie. It won't end well.
 * travel through time!"
 * panic!"
 * This one is the correct one
 * open that door!"
 * be late for your brother's wedding!

...And it will remain a Stable Time Loop

 * The viewer will see Twilight *still* commit said social mistake and still travel back in time, where upon her return, her friends will tell her it wasn't anything to get worked up about.
 * Furthermore, future Twilight was trying to tell present Twilight not to go to the Canterlot archive to research time travel, and at the end she will still go back to try to give the message to herself, after which another character will inform her that she could have avoided the entire mess if she had just not gone back in time at all. Have you gone cross-eyed yet?
 * Not exactly, but I just don't know what went wrong.

The lesson of the episode...
... Will be that friends, family, and self-identity don't just come as folks who look like you, but those who love you and will do a lot for you.

The episode will be a HUGE Tear Jerker with a Crowning Moment of Heartwarming
Rather than being mean to Spike, the other dragons actually welcome him and extend hospitality towards the Main Six. Twilight will feel that the Dragons treat and respect Spike better and decides Spike would be happier with his own kind. The others try to talk her out of it but they end up seeing her point when Twilight references past episodes in which Spike was left out. Twilight and the gang bid a tearful goodbye to a confused Spike, and when Twilight gets home to the Library, Spike's waiting for her right there.
 * Wait, wait, wait, how was this 'correct'?

Fluttershy will be forced into working on the weather team.

 * Either by Rainbow Dash or somepony else (her parents perhaps?) in order to live up to her pegasi lineage.
 * Since previous episodes have shown how she can match Dash's speed at times, she could get recruited because others think she'll work well with her friend.
 * Aside from the general idea that Fluttershy was forced to participate because she's a pegasus, neither guess listed seems completely correct.

The episode will involve a literal hurricane

 * Tornado actually, but since it was used to suck up water, it could be a hurricane anyway...

== "Ponyville Confidential" will involve a newspaper, and it will be called "Equestria Daily". ==
 * And maybe there might be a reference to the Cereal's, Seth's and Phoe's OC ponies.
 * The expanded synopsis has confirmed that the gossip column is in a newspaper (specifically, a school newspaper) but no word on what the newspaper is called.
 * Screenshot #56 from Hasbro's Web Games My Little Pony Friendship Express Train™ Puzzle Adventure possibly Josses this, if it is indeed from this episode.
 * And now a Hub commercial has come out, clearly showing the paper's title as three short words (with the first word appearing to be "Foal"). Not 100% Jossed yet, but just about.
 * A new clip from the aforementioned game confirms that the paper is called the Foal Free Press, so that half of the guess is now Jossed.

== Screenshot #54 from Hasbro's Web Games My Little Pony Friendship Express Train™ Puzzle Adventure is from this episode, and... == The newspaper's picture of Celestia with cake is an ad for the contest in the next episode.

The culprit is....

 * ..... Trixie!
 * ..... A Parasprite!
 * ..... Spike!
 * ..... Chuck Testa!
 * ..... Magneto!
 * ..... Bon Bon!
 * ..... Gummy! Watch him steal those corncakes here.
 * ..... Red Herring!
 * ..... Discord!
 * ..... not revealed!
 * ..... an orignal character!
 * ..... none of these guesses!
 * ..... Derpy!
 * ..... Gilda!
 * ..... Gummy!
 * ..... Everypony!
 * This is the correct guess... in a sense...
 * ..... The Butler!
 * ..... It's Decade's Fault!
 * ..... Celestia! (And possibly a deliberate foreshadowing based on her candid photo in "Ponyville Confidential" of wolfing down cake)
 * ..... the Griffon cook! Because he has a moustach!
 * ..... Joe Barbera!
 * ..... Princess Cadence!
 * ..... Winona!
 * ..... Lex Luthor!
 * ..... Agatha Christie! To collect her debt!
 * ..... Your Mum!
 * ..... The moose! It's always the one you'd least suspect.
 * Possibly supproted by the enourmous size of the missing section of the cake, combined with the grooved design that appears to indicate a large chomping bite of some sort.
 * ..... Me! I ate the cake!
 * ..... Pinkie Pie!
 * ..... The third person on the cast list of the TV page in newspapers!
 * Not in newspapers, but the third person on the cast list of the show's own credits is Fluttershy (and Pinkie Pie)'s voice Andrea Libman.

== Screenshot #30 from Hasbro's Web Games My Little Pony Friendship Express Train™ Puzzle Adventure is from this episode, and... == Pony Joe, who appears in a screenshot almost certainly from this episode, has something to do with the donut cake.

Celestia's nephew is real.
Although most fans have dismissed Rarity's dream stallion hunk as a fantasy brought on by reading too many tabloids, there is strong evidence he does indeed exist. His cutie mark (in Rarity's fantasy) is an eight-pointed star. The astronomical model of Equestria's planetary system in the courtyard at Canterlot shows the planet in the center, with sun, moon, and a few other objects around it, including a spiky thing with a ball and some curvy lines. It looks like a comet with a star attached to it for some reason; the star is seven-pointed, but has an almost identical shape to the nephew's cutie mark.
 * Confirmed, his name is Prince Blue Blood and he's a royal Jerkass.
 * Sort of. Word of God says that he's the "great, great, great, great, great, great, great, great, great, great, great, (and possibly even more greats) nephew on Celestia's and Luna's mother's side, about 52 times removed, roughly speaking."

Discord is...
We have a name for a new villain in Season 2 (the first two episodes anyways), but all we have a name! List any and all guesses here! Discord is...
 * The evil magic that turned Luna into Nightmare Moon (Not confirmed or jossed, needs to be moved to a third page).
 * A collective of six evil versions of the Mane Six, forming the Elements of Discord.
 * Celestia's first "most faithful student"(Not confirmed or jossed, needs to be moved to a third page)
 * Big Bad minion
 * A dragon (this is a theory created by bronies who gave a close, practically frame-by-frame examination of the "20% Cooler" scene from the promo: apparently in the upper-right corner of the screen, behind Celestia, there is a stained glass window which shows a stylized battle between the Princesses and a dragon).
 * Higher-res images of that scene have revealed that the creature in the stained glass window is less of a dragon and more of a chimera...thing. Its featured prominently in all the windows (both colored and white) except one, which depicts the Mane Six defeating Nightmare Moon, and one of the windows shows it manipulating ponies. The hallway is assumed to be an area of importance, so whatever that creature is it most likely represents Discord. One more week and we'll find out for sure!
 * We have a winner! First look at Discord.
 * And the official name of his species is "Draconequus."
 * Combining two WMGs, Discord is an evil alicorn but he fights using corrupted versions of the Mane Six (either polar opposites or just their elements taken to the extreme).
 * An Eldritch Abomination (Not confirmed or jossed PER SE, needs to be moved to a third page)
 * A literal Anthropomorphic Personification of Discord. He's refered to as "the spirit of Disharmony".

Princess Celestia can no longer use the Elements of Harmony
Princess Celestia has been the sole ruler of Equestria for 1000 years. She is a semi-divine being at least with both pegasus wings and a unicorn horn. She has subjects, worshipers and a few students but no actual friends. As such she can no longer activate the Elements of Harmony. She gets Twilight Sparkle to send her what she has learned each episode because she can't even remember what friendship is like anymore.
 * It's probably more the fact that the other ponies who wielded the Elements of Harmony with her died of old age nearly a millennium ago. You probably can't get another shot at it with Replacement Goldfish friends.
 * Makes sense. Given that it seems normal ponies age, she probably can't sustain true friendship with people she knows she will have to watch grow old and die. Even if she can, it's likely the emotional trauma of having to banish and imprison her own sister, or the mystic symbolism of the act itself - let's face it: regardless of how good your reasons are, banishing and imprisoning your own sister is one of the harshest, coldest things you could do - has robbed her of either the required magical ability, personal fortitude or both.
 * Really, I think it was because she used them for the wrong purpose. The Elements of Harmony are meant to help two ponies understand each other and get feelings of friendship through. When that didn't work, Celestia drained their energy to give her the power to seal Nightmare Moon into the moon. However, since they were used incorrectly, they became powerless until the Secret Test of Character at the Everfree forest brought forth ponies who represented the elements to properly recharge them. Now used for their proper purpose, they have regained their potency.
 * I'm not so sure. The Elements of Harmony are meant to maintain harmony. Nightmare Moon's rebellion was an express attempt to overthrow the harmony of the universe itself: the balance of night and day, light and dark, sun and moon. Celestia used the Elements to restore cosmic harmony, as opposed to harmony within her own family.
 * Alternatively, Celestia couldn't use the Elements of Harmony to restore Luna, because Luna turned into Nightmare Moon because she was rejected by her subjects, not by her sister. As such, only her subjects, in the person (pony?) of Twilight and her friends, could bring her back.
 * Confirmed in the Return of Harmony. The same is true for Luna.

Discord's actions will get more chaotic and cruel the longer he's let loose
We're already seeing this. His first act was just to make it rain chocolate milk from cotten candy clouds. Then he's ended up turning Ponyvile on it's head and making it a chaotic (though still somewhat silly) mess (though admittingly, the floating houses were kind of scary...). And he outright says those are only his "first changes". It's implied that 1000 years he did a lot worse things, he just gets progressibly more terrible, starting from silly and gradually working his way up to the stuff he put the Mane Cast through. We'll see this in the second episode as well.
 * Appears to be true.

Applejack will be the first to break out of the spell.
She's the only one who seems to be aware that that she's not acting normally.
 * She was the first of Twilight's friends, after Twilight went through a Despair Event Horizon.

How Discord will be defeated...
Just give your guesses, since we've all got this on our minds I assume.
 * He'll be turned back to stone with the Elements Of Harmony.
 * This one's the winner.
 * He will be killed in some fashion (in family friendly manner of course)
 * He'll be forceably turned good.
 * Well, he THOUGHT they were planning on doing this, perhaps because he knew that's what they did to Luna/Nightmare Moon.
 * The CMC will have something to do with it.
 * Discord's brainwashing methods seem to be related to a pony's cutie mark (Applejack with apples, Pinkie Pie with balloons, etc.) He will try to brainwash the CMC but will fail to find a method due to their lack of cutie marks.
 * While the Mane Six will be the ones to deal the final blow, the Princesses will deliver a key Big Damn Heroes moment. Discord will probably start gloating about how he was the one who corrupted Luna 1,000 years ago ("Well, if it isn't dear little Luna! Still in your sister's shadow, right back where you started, I see. Tsk, tsk, and I had such high hopes for you..."), which, as he will quickly discover, is a very bad idea.
 * The Mane Six will inflict an Humiliation Conga on him by tricking him into accepting a "game" where they make the rules, allowing them to win back the Elements Of Harmony and defeat him while humiliating him at the same time.
 * He'll end up suffering Sanity Slippage himself as a result of someone pointing out he only won through an ORDERLY and complex plan, not by chaos and disharmony and that all his plan did was make their friendship stronger in the end after they reforged it.
 * Discord will suffer a Villainous Breakdown and go One-Winged Angel before being defeated.

Discord's defeat will be a full blown Shout-Out to Tirek's
Let's see, the Elements Of Harmony have already been used to homage the Rainbow Of Light once and Discord is a Complete Monster like old Tirek and wields the polar opposite of the thing needed to defeat him. Why not go all out and make a full homage? Perhaps with Discord doing something simular to Tirek's Rainbow Of Darkness and it clashing with the Elements Of Harmony. This will surely invoke a Squee reaction from older fans if it happens. Doesn't have to kill him, but it'd still be awesome.
 * Not sure if this counted or not, but he did taste a rainbow.
 * If you listen, the music is actually simular and like with Tirek, the rainbow turns into a World-Healing Wave that undoes his changes to the world.

Discord didn't corrupt Twilight as revenge on Celestia
He knows so much about the Mane Cast, it only makes sense he'd know that Twilight is Celestia's dearest and most loved student. So by breaking apart their friendship but leaving Twilight to suffer the crushing lonelyness going with knowing her friends are twisted shells of their former selves and don't care for her anymore, he's getting vengeance on Celestia for imprisoning him by forcing her to watch her student suffer that way. Likely, we'll see him do something like play on Celestia's guilt over what happened to Luna that broke their bond with the Elements Of Harmony and permitted him to escape, try to get her to accept the blame for the pain and suffering her dearest student is going through in a Mind Rape to her.
 * He did do this to effect, but not because the Princess had anything to do with it.

Normally, the Mane Cast could use the elements if they were just there...
That was kind of the point of the season one pilot: the elements can't be destroyed as long as the spirits of the elements were still around. Discord knew this and used manipulation and magic to turn each pony away from their respective element before they got together. Had they gotten together before he got to them, they could've summoned the elements on their own. But since Discord made it so they weren't expressing the elements (making Rarity greedy, Fluttershy mean, etc.) they won't be able to summon the power of the elements. They will be able to again once they start showing the traits of said elements.
 * Kinda confirmed?

Discord is a Trickster God or mischief spirit
From the new clip that's been released, he's extremely powerful but considers everything a joke and part of his game. He clearly enjoyed the scare he gave the Mane Cast by taking away their horns and wings. He was also sealed away for some reason. He's a trickster god or mischief spirit, thus why he's so powerful and is messing with them the way he is.
 * He's pretty much this.

Discord chose not to Mind Rape Twilight on purpose
Although the game has ended, he wants to see Twilight break on her own now that they have lost and her friends are no longer who they once were. Remember that the subtitle of the series is Friendship is Magic.
 * Alternatively he knows that he can’t Mind Rape Twilight because she’s the Element of Magic/ Friendship an no foul magic can change the power of true friendship. He can only defeat her if she abandons them willingly.
 * He didn't need to do anything but corrupt the other 5, but he ended up breaking her spirit anyway.

Princess Luna will take on her Nightmare Moon form again
but not become evil. She's spent all of season 1 training to gain control of this form.
 * She actually did. Although it was to scare some children for fun.

The reason why Apple Bloom gets Cutie Pox...
Is because she tried to get her Cutie Mark with magic.
 * True! She consumed a magic potion.

The Best Pet Ever.
Given that it apparently involves Dash finding a pet and she's evidently holding a race or a contest... she will become attached to the worst of them all (ie, a turtle, an attachment she will try to deny in favor of the speedier, much more athletic Cheeta cub, or something similar) or something "silly" and "undignified" like... a badger. Eventually, she will go with the one she grew attached to, because it will either in the case of the badger, show its badassery, or in the case of the turtle, it will be in danger somehow.
 * Pretty much confirmed now that the new episode has come out. She had a race and a turtle became her pet because of a Crowning Moment of Awesome on his part. Also the turtle's name is Tank. Let the Cowboy Bebop jokes commence!
 * TORTOISE! It's a tortoise, just look at the elephant-like feet...

Episode 8's Masked Mare speculations
Synopsis: There is a new hero in Ponyville who is masked and stealing Rainbow Dash's thunder.

Right now, my guess is that it's Derpy. I do remember hearing that Derpy would have scripted scenes and that she would be considered a "Where's Waldo"-type challenge. Maybe all the characters, even the minor background and one-shot characters, will show up at one point during the episode and but we'll never see Derpy till the end when she's revealed.
 * Derpy can't be the Mysterious Mare. Derpy has googly eyes. The Mysterious Mare wears a mask. How could she see with googly eyes under a mask? There is no way mild-mannered mailmare Derpy Hooves could be the Mysterious Mare.
 * Except that her eyes have appeared un-derped in the past. Heck, a good portion of her season 1 appearances have her un-derped and even in season 2, she occasionally shows up un-derped.
 * Alternatively, its Spitfire or another Wonderbolt secretly testing Rainbow Dash for whatever reason.
 * Maybe it's Trixie, looking to change her own image after the Ponyville incident.
 * Or she's taken after Major Man, and steals Rainbow Dash's thunder by causing the trouble she then solves.
 * She could also be going by a different name.
 * Perhaps she's one of the Canon Foreigners and will become a Canon Immigrant.
 * Maybe it's even one of the mane cast. If the trend of some of the ponies not appearing in episodes continues, this could work.
 * a completely original character
 * never revealed
 * And said Un Reveal shall spawn a million fanfics.
 * , may still spawn fanfics.
 * Mayor mare!
 * One of the princesses
 * Rainbow Dash as part of the most elaborate prank ever.
 * Two or more mares in identical disguises, seemingly performing Offscreen Teleportation.
 * Also !
 * And the winner is:
 * So, ? Not bad, I guess.
 * One of the princesses
 * Rainbow Dash as part of the most elaborate prank ever.
 * Two or more mares in identical disguises, seemingly performing Offscreen Teleportation.
 * Also !
 * And the winner is:
 * So, ? Not bad, I guess.
 * Also !
 * And the winner is:
 * So, ? Not bad, I guess.

"Sweet and Elite" will involve Prince Blueblood.

 * Ah, no. After what happened at the Gala, she'd rather choose a bowl of prunes than Blueblood.
 * He might, at least, make an appearance. Maybe a swift gag or something.
 * Confirmed. He makes a couple cameos during Rarity's song.

Rarity will write the Friendship Report for "Sweet and Elite"
'Cause, you know, it's about her making an important decision related to her friends.
 * Confirmed, though she ends up telling it directly to Celestia rather than writing it.

Spike will have his own breakdown soon.
If his "Spikely Whiplash" moment in the Owl episode doesn't count as a breakdown, then the chances are one of the season 2 episodes will have him snap.
 * Maybe if too many episodes have him appear for the sole purpose of transporting messages, he could start feeling overworked and overlooked...
 * More or less happened with "Secret of My Excess".

Spike's greed and growth spurt in "Secret of My Excess" are connected somehow.
Why? Um... Discord?
 * Might be regular growing pains and/or a part of dragon puberty.
 * Confirmed, dragons growth is a result of greed, which causes them to get greedier.

Rainbow Dash will get a pet.
once she starts to feel jealous of her friend's pets, she will search for her own pet. i bet for a turtle.
 * I don't think RD has the time or patience to be a good pet owner. Not good with kids, not good with animals.
 * Pretty much confirmed by the upcoming episode "May The Best Pet Win".
 * Confirmed! And it was a Turtle!... or a Tortoise.. whatever.

Equestria is a lot older than Celestia's reign.
Celestia and Luna used the Elements of Harmony to make themselves into Physical Godesses and were both granted the title of princess. Along the way, there was a disagreement; Luna tried to put herself above Celestia. There was a bitter war over who would rule. In the end, Celestia won and Luna was banished to the moon, where she began forming herself into Nightmare Moon.
 * Partially confirmed. Discord is said to have ruled Equestria before he was defeated and usurped by the sisters using the Elements of Harmony.
 * Maybe not though. Under Discord's reign, there may have been so much chaos that the whole notion of the coherent passage of time may have been out the window. We saw Applejack uneat an apple, and the sun and moon rise and set in very rapid succession, you may recall. Perhaps as Discord's hold on reality progressed, time would have become more and more random, flowing at different rates and directions for different ponies. Discord's reign may have been a state of primeval chaos in which time was not a meaningful concept. In that case, it is impossible to say that anything is older than Celestia's reign, as that may have been the beginning of time.
 * "Hearth Warming Eve" pretty much confirms that the three pony tribes discovered and settled Equestria before the two sisters took the reins (no pun intended).

In "Family Appreciation Day", Granny Smith will turn out to be a Retired Badass.
There's really only two ways this can work out, either she turns out to have a very awesome past that Applebloom will be shocked about or...
 * Confirmed in that Granny, on her own, discovered the means of harvesting Zap Apples and making Zap Apple Jam just right, and...

== "Family Appreciation Day" will reveal that Granny Smith's past is completely mundane, but surprisingly important and/or interesting. == The aesop, of course being that even if someone doesn't have some impressive or awesome background, they can still be important in ways you don't expect.
 * Confirmed as well, given that Granny's family at the time was the reason why Ponyville was founded.

"Family Appreciation Day" will include flashback to the days of Granny Smith's youth.
Possibly with "Mister Sandman" Sequence of Ponyville back then, parodying real life old fashions the same way as Cheerilee's school photo. Maybe it would even turn out that GS used to be a beatnik, flapper or whatever was popular at her times.
 * Confirmed, though a bit farther back than that.

The twins will say their first words at some point in the episode.
Most likely at the end, and the word being something Pinkie said, or even her name.
 * On the nose.
 * Not stated to be their first words, though.

Applejack will have a Ten-Minute Retirement
If you pay attention to the dialogue in the clip, they discuss about.
 * Pretty much confirmed

The Flim Flam brothers are twins and perhaps palette swaps of each other

 * Alternatively, they could be Fat and Skinny.
 * Revealed to be twins, one just opting for facial hair to make their difference

The Flim Flam Brothers win, but will be revealed to have cheated
Either directly afterward or after trying, and failing, to run Sweet Apple Acres. The Aesop will be something about cheaters never prospering. Just look at where Flim Flam comes from to see the source of this WMG.
 * Kinda... They skimped on quality to increase quantity. Which really screwed them over bad.

The Flim Flam Brothers will cross the Moral Event Horizon
Let's face it, trying to take somepony's livelihood away from them is darn close already.
 * Alternatively,they realize just how bad snatching the farm away from the Apple Family really is, and give it back out of guilt.
 * Didn't happen. They just ran off to possibly con another town.
 * However, the original WMG is confirmed, (though YMMV), they definitely crossed the line by rubbing their victory, and the loss of the Apple Family's livelihood, in the Apple Family's faces. If AJ hadn't held her back, Rainbow would've kicked their flanks for it.

Iron Will will be a Drill Sergeant Nasty as well as a shout out to Gunnery Sergeant Hartman.
Bonus points if Mr. Ermey actually does the voice. He's worked on kids' shows before.
 * Well, he's certainly a Drill Sergeant Nasty.

The training will turn Fluttershy into a bitch like in the Return Of Harmony.

 * Pretty much. Perhaps even worse actually.

Fluttershy will be more assertive, but in her own unique way
While she's likely to remain the kind & quiet pony we come to know & love, she'll have more of a backbone. The episode will start & end similarly showing how she developed over the course of the episode.

Fluttershy will fail miserably at asserting herself most of the episode...
And every time she does, Iron Will will be a Drill Sargeant Nasty and a bully towards her, being Fluttershy, she doesn't defend herself...Until Iron Will bully's her friends the same way and meets Mama Bear mode Fluttershy.
 * Kinda true, although there wasn't too much interaction between Iron Will and the other characters.

Iron Will will be excessively manly
Perhaps even being The Ahnold.
 * Very much so.

Fluttershy's personality will temporarily go a complete 180.
She'll become goth. It'll be funny and amazing at the same time.
 * Goth part untrue, other parts, yes.

Iron Will's training will turn out to have Gone Horribly Right
Iron Will successfully helps Fluttershy grow a spine, but she takes it too far and becomes an arrogant Jerkass and snaps out of it when she gets a What Have I Become? or a What Have I Done moment (which will most likely be her snapping at Angel, the Cutie Marks Crusaders, or one of her friends)

There will be another CMoA for Fluttershy
After all, so far two episodes that center on her that ended with her getting one.

Twilight will be shown sending the message back.
Either at the end of the episode, or in a later one.

== Both the dragon from "Dragonshy" and the dragon from "Owl's Well That Ends Well" will appear in this episode. == Just throwing it out there.
 * Don't forget Steven Magnet.
 * Possibly partially confirmed by a preview clip: one of the sleeping dragons appears to be the one from from "Dragonshy".
 * Both dragons did appear to appear in the episode.

Spike will try to go alone, but...
... Some member(s) of the Mane Cast will sneak along to watch him out of a (legitimate) concern for his safety. After all, he is just a baby dragon, and past episodes have shown that dragons can and will be aggressive towards their own kind.

This episode will show at least a few different types of dragons.
So far, the only two dragons we've seen other than Spike have been basically identical, aside from color. Considering the Art Evolution the show has gone through between seasons one and two, this episode will hopefully depict dragons with various sizes, body types, and even different breeds.

Twilight will actually support Spike's decision to join the dragon migration.
She might find it to be a good oppurtunity for him to learn more about other dragons, and she'll of course insist to come along herself both because she wants to look after him, and because it is an excellent oppurtunity for her to learn more about dragons herself.

This pony will play an important role in the episode.
But what will he be?
 * A wing trainer for Fluttershy.
 * The pony that accidentally ruins the tornado so Fluttershy can save the day.
 * a Running Gag joke character
 * Running Gag character, nothing more.
 * Derpy's boyfriend.

The CMC's gossip will include true information about ponies they're close to.
For instance, Apple Bloom and Sweetie Belle sharing some of their siblings' actual secrets.
 * Sadly yes.

The CMC's gossip will include Call Backs to various older episodes.
Such as gossiping about Fluttershy's old modeling career, or how the results of Iron Will's lessons, or the events of "Hurricane Fluttershy". And those are just examples for one of the main cast...
 * Does Big Macintosh and Smarty Pants count?

One of the hurtful stories involves Fluttershy
A preview shows her crying up a storm, and it's been mentioned (and shown in a previous episode) how sensitive she is.
 * Yes. The story is that she has Tail extensions.

Diamond Tiara will manipulate the girls into writing hurtful stories
By convincing them either no one is going to be hurt or something else. Naturally, this is just her way of getting payback at them. They're still to blame, however, for believing her, but in the end, after figuring it out, their last story will be about her having manipulated them, but she's too complacent by that time to notice until its published.
 * She did blackmail them by having embarrassing photos, but the last part doesn't come true.

Parents will show up in the next CMC episode(s).
If they will try explore past of other characters parents must be seen at some point, unless one previous WMG about parents is true.
 * Partially confirmed - in "Cutie Mark Chronicles", we see Pinkie Pie and Twilight Sparkle's respective parents.
 * Sweetie Belle & Rarity's parents make an appearance in "Sisterhooves Social."

Villains will only have a limited presence in the series.
Mostly to season openers and finales with most of the episodes in between still focusing on the slice-of-life elements.

Season 2 will have an episode in which:
Spike will yearn to learn about his dragon parents, or substitute parents, who believe in The Spartan Way. Eventually, he will realize that their way doesn't fit him, and he will have a montage of growing up with Twilight at Canterlot. This will serve as an Aesop about adoptive parents.
 * They actually did an episode very similar to this in the 80's series.
 * Alternatively, maybe his dragon parents aren't that bad at all, but even then, Spike still misses Twilight.
 * Dragon Quest.

Season 2 will have an episode where Spike goes through Dragon Puberty
Specifically: getting his wings and possibly horns. At first he'll think that he's awkward and ugly and possibly try to run away again when his clumsiness ruins some important event, only to eventually be reassured that his friends still love him anyway and went through similar phases only to come out okay themselves.
 * As mentioned under Art Evolution and Vocal Evolution Spike is one of the few characters who is visibly aging as the show progresses. Perhaps dragons age at different rates than ponies and he will eventually start going though larger growth spurts as he becomes an adolescent. It's possible his voice actor may be recast too.
 * A Base Breaker moment if I ever saw one.
 * A strong likely chance given the Spike-centric upcoming episode "The Secret of My Excess". Whether this is just growing up or growing large remains in question.
 * The Secret of My Excess

There will be a Christmas Episode.
And the Equestrian equivalent of Santa Claus will be a reindeer.
 * Real or not, they do have some sort of Santa (judging by the costume display seen in "The Ticket Master").
 * Hearth's Warming Eve

As an addendum to the above, someone will make a clone of Robot Unicorn Attack.
It'll star Rainbow Dash, with the plot being that Rainbow Dash, wanting to be a more versatile athelete, trains herself to be the best runner in Equestria. Crashing will not end in Rainbow Dash dying, but hospitalized, and it will actually be beatable (but Nintendo Hard).
 * Mostly confirmed

"The 20% Cooler" scene from promo is from the first episode or its second part.

 * Pretty much confirmed.

We're all insane
Look at what we've become! Nine massive folders of pony WMGs? Extensive Episode guides? A huge list of fan fics? An elaborate character page (I'm partly responsible for the Background Ponies section!)? All after ONE season? Where does it all go? Where does it end? Is the cake a Lyra? I must know!!... I ...I need to hug Fluttershy...
 * The ponyless summer drought will do that....
 * What must you think now that the nine folders of WMGs have become several separate pages in their own right...
 * Their are 10 pages and now three tropes inspired by MLPFIM
 * That this guess is confirmed, that's what! Its OK though, I still love all our crazy Brony Tropers.
 * Don't forget the bronies harrassing Yamino for not liking Derpy's voice and her Fan Nickname made canon.
 * If the Daring Do page is any indication, I think we've transcended mere insanity at this point.
 * The line between Genius and Madness is only separated by degrees of success. Perhaps we're all geniuses?

Season 2 will prove to be a base breaker due to Executive Meddling.
We know that Lauren has reduced her involvement with the show in the second season; she says she has full confidence in the crew working on it, but she would sort of have to say that wouldn't she. I'm worried that the show may start to move away from Lauren's brand of storytelling back toward the sort of stereotypical "girlie" stuff that Lauren was trying to get away from in the first place. This will divide the base as many old-school bronies don't like it, but the target audience doesn't care as much.

(I'm very hopeful that the act of making this prediction will make the universe strive to prove me wrong.)
 * The "Equestria Girls" song proves that Hasbro (or at least the Hub) knows about the bronies, so hopefully they will continue to make it appeal to them. I almost feel that they will try too hard and fail that way.
 * But that promo was put together by the Hub, not necessarily by the people actually making the show itself. You can't tell anything about what the show's staff will do from that.
 * Yes, but so far the people who make the show have earned our trust. The promo suggests that Executive Meddling probably won't make the show take a turn for the worse.
 * The show's awesomeness is not all down to Lauren. Daniel Ingram, the animators, the writers, even the voice actresses, they all play a part in making the show what it is. And despite what Hasbro might think, little girls aren't idiots. If the show changes for the worst, they'll get as upset as the older fans, they just won't complain on the internet.
 * Actually, a clarification that Lauren posted suggested that one of the reasons she's not so involved is that the things she needed to contribute to Season 2, such as basic episode ideas, were pretty much done. So her ideas will be implemented, hopefully, and there's the rest of the very talented staff remaining. This troper is optimistic about season 2.
 * The Hub tends to really go with shows that take advantage of the Periphery Demographic. I don't think they'll want to risk messing with one of the shows they've got that does that the best.
 * It has been established that Hasbro don't get involved further than very specific an little things, like the "princess" thing.
 * After "Derpygate" can we call this one confirmed? Not quite for the same reasons as the original guesser claimed, but...

It will be when Cerebus Syndrome will strike
It's a two parter, much like Return Of Harmony and Friendship Is Magic.
 * Confirmed... kinda. It's more:

Discord will have nothing to do with this
"Send clones to trash wedding" is a step down from his usual M.O. of "Total chaos across Equestria".
 * However, the clones go hand in hand with his "Mind Screw the protagonists" tactic.
 * It seems unlikely Discord would return. Hasbro and the Hub tend to keep tabs on the fanbase. If the series most popular villain was returning, don't you think they'd be advertising that fact?

Cadance's Dark Secret
Come one, come all! Hurr-ay hurr-ay! Eve-ry pony place your bets! Lucky win-a gets a nifty prize!!
 * Definitely something evil! Yeah, its subtle, but I mean look at her eyes! There was no pony before her that used eyeliner (save maybe Rarity...)
 * Don't forget that Celestia's eyes are pretty much the same (interestingly, Luna's aren't).
 * Only Cadance will consider her secret to be important.
 * Her alicorn-ness is due to a magical artifact. One she stole.
 * Something Cadance is unaware of. She will be behind some bad happenings, but it turns out in the end she has no idea she is. Perhaps she's got a Nightmare self like her aunt Luna, but it's more of a Split Personality as opposed to an alternate form or she's a newly ascended Alicorn who can't control her powers yet.
 * Cadance is Older Than She Looks, and Shining Armor is her Second Love.
 * Or the reincarnation of a past love.
 * It's a mistake -- the truth is more innocent than Twilight realizes, but she's so worked up over the impending marriage she blows it way out of proportion.
 * Invert that, and you technically have what part of the plot is about.
 * Cadance is Discord.
 * In a Princess Cadance mask and bodysuit, no less. And when the Mane Six unmask him, he'll be dragged off muttering, "And I'd have gotten away with it too, if not for those meddling ponies!
 * She isn't actually Celestia's niece, and comes from a far-off land.
 * Cadance was the one who allowed Discord to take over Equestria in ancient times, however, that's only half the story, the other half is she's the princess from the Hearts And Hooves Day story and only gave it over to him due to being under the influence of the Love Poison, being too in love with her prince to realize what she was doing. Celestia hid this fact from the public to protect her niece, but Cadance is wracked with guilt about it.
 * The Cadance that appears at the wedding is an impostor. The real Cadance has been kidnapped. are you a bad enough mare to rescue the princess?
 * Alternately, Cadance is a clone originating from the same place as the Mane!Clones.
 * Cadance is actually Trixie. She's been training her talents (performance and illusion spells) to fool everyone...except Shining Armor. You see, he first met her while he was on patrol and Trixie was wandering through Canterlot, penniless and hopeless. Armor gave her a place to stay for a few days, and Trixie slowly started opening up to him. So while "Princess Cadance" is a sham, the wedding, and their love, isn't.
 * Partially correct: Cadance  is voiced by Trixie's VA.
 * Cadance is a guy (Yeah, if only.)
 * Cadance is a guy (Yeah, if only.)

The clones aren't as major a plot point as they seem
They're just going to show up for one scene on accident, get their flanks kicked, and the plot will continue. It may have something to do with the plot, just not as major as it seems.
 * A Part 2 clip seemingly unrelated to them has "clones" as one of its tags, though...
 * The clones were the Changeling army, but they weren't that important to the plot.

Everypony who is anypony will be there, including Luna.
In the trailer, we can see Celestia and Shining clearly waiting for the bride. Somepony of equal importance has to walk Cadance to the altar.
 * One of The Hub's wallpapers does include Luna, which suggests that she'll make some kind of appearance.
 * She also appears in the background of the Web Games DJ Pinkie Pie, making it even more likely that she'll be in at least one of the episodes.
 * The aforementioned desktop wallpaper has been adapted into a background used on their home page, further increasing the likelihood of her appearing.
 * The aforementioned desktop wallpaper has been adapted into a background used on their home page, further increasing the likelihood of her appearing.

Cadance created the clones as bridesmares.
She originally wanted Twilight and her friends to serve as her attendents; however, after being offended by something they do, she 'fires' them and creates the copies to serve in their place. There's originally only one of each, but circumstances grow beyond her control...

Twilight dislikes Cadance.
She's glowering at her in this promotional image. Perhaps Twilight disapproves of the wedding for some reason?
 * She did, since it wasn't the real Cadance!

Twilight's solo song will be in this episode.
And it will be about her relationship with her brother. (No, not like THAT!)
 * The Hub's Wedding Memory Game printable and one of their wallpapers do respectively show a microphone and Twilight with the microphone.
 * Confirmed!

And the catcher of the bouquet is...
Cheerilee, who smiles nervously at Big Mac
 * The Hub's Pin the Bouquet on Rarity printable says that.

If anypony objects to this union, Speak Now or Forever Hold Your Peace...
Look, this is a two-parter season finale about a huge wedding that goes off the rails. It's not a question of whether the line will appear. It's a question of how.
 * The line will be spoken by:
 * One or all of the Mane 6.
 * Seems like it was Twilight herself, and also...
 * One or all of the CMC.
 * One or all of the Mane 6's clones.
 * Some other clone. You know, just in case there are more clones running around.
 * Spike.
 * Discord
 * Princess Luna.
 * Derpy.
 * Some Stalker with a Crush for either Shining or Cadance.
 * A new villain.
 * Trixie.
 * Magneto.
 * There won't be one.
 * Luna
 * Either one of the wedding duo
 * a Canon Immigrant
 * Celestia
 * someone none saw coming.
 * The Real Cadance!
 * Derpy.
 * Nyx--((Flame War))

Princess Celestia will try to give each of the Mane Six the best night she had wanted but not gotten at the GGG fiasco.
We see Pinkie as a DJ, and Dashie's hanging out with the Wonderbolts.

Twilight's unease with Cadance marrying her brother is due to being baby set by her as a filly
It's been explained this is how they met, so Twilight knows Cadance already. That's the problem; Cadance, as her baby sitter as a foal, would probably be someone she considers more like a sister (emotionally), so seeing her brother marry her could be rather uncomfortable.
 * While there was a relationship issue, it certainly wasn't due to that.

Celestia will scold (or worse, punish) Twilight for jumping to conclusions or otherwise accusing Cadance (initially)

 * Confirmed. She gave Twilight a stern "You've got a lot to think about" as she leaves the wedding room.

The wedding, despite all the clones and whatnot, will end rather happily
This theory is based off several clips and the order they will probably go. In one preview clip, Twilight is by Shining Armor's side while the wedding starts off, complete with singing birds and flower girls. A similar clip lacked Twilight Sparkle, singing birds, and flower girls. In that clip, something goes wrong (the lack of a ringbearer) while the former clip has no screwups. This proves that something goes horribly wrong in the latter, and by the time the former happens, everything is sorted out. Not to mention that large celebration, with Pinkie and the DJ and all that. It's either a pre-wedding or post-wedding party.
 * Once the Changeling threat was eliminated, then yes, this did happen.

Half these theories for this episode will be jossed
If this show has proven us anything, jumping to conclusions isn't the best way to go, given the recurring theme of jumping to conclusions (Lesson Zero, It's About Time, MMMystery on the Friendship Express), this is probable.
 * Half? Try most. Many guesses end up being far darker then what is shown eventually.

== "A Canterlot Wedding - Part 1" and "A Canterlot Wedding - Part 2" will be released on DVD. == No, not that promotional media screener, but another Shout Factory release; they do have plans for at least one more. The two biggest toy themes of Season 2 are the Friendship Express Train and the Pony Wedding, and since their first DVD was themed around the former, it'd make sense for another DVD to be themed around the latter. Plus, the two-parter's last song "Love Is In Bloom" has an unreleased extended version, which could be used for a sing-along on the DVD (like with the Theme Tune Extended on The Friendship Express).
 * Said extended version has now been released as a music video on Hasbro's website, but it could still be used for a sing-along.
 * And now Hasbro has taken it down from their site. Perhaps it will be included on a DVD and they want it to be exclusive to that.
 * All but confirmed: Royal Pony Wedding is to be released on August 7, 2012.
 * Now confirmed!

"Eeyup."
