Neptunia/Headscratchers

Have they ever given a reason why this game is a Play Station 3 exclusive? As noted on the main page, it's really weird to for it to be a console exclusive with its premise and it's not unreasonable to think it could made for both the Xbox 360 (what with both system generally sharing games) and the Wii U (giving Nintendo a system with specs enough to play it).
- Compile Heart usually releases games for the Play Station 3 to be released on the 360 about a year later, giving more content. Already happened with Cross Edge as Cross Edge Dash released only in Japan.
- The regular Wii should be able to handle it too. The PlayStation 2 could handle KH, and since the PlayStation 2 and Gamecube are roughly equally powerful (and the Wii is a slightly more powerful gamecube) there shouldn't be any reason why this can't be ported to Wii besides favoritism against the Wii (and Xbox if they dont port it to that). Also, there is that the Wii could handle Legend of Zelda: Twilight Princess (correct me if I'm wrong about the favoritism...)
- Different console makers have different qualifications for developers and different editorial guidelines for video game themes. Some console makers prefer established businesses staffed by experienced professionals, some require developers of download games to work with established publishers of disc games, and some may fear backlash from gamers over anvilicious delivery of the Digital Piracy Is Evil aesop. In fact, console makers' shunning of amateurs and startups is what leads to (non-pirate) use of things like R4 and CFW in the first place.
