I say the big KH game will be on PS3, not on the Wii. It's plain to see that Square/Enix is still unwilling to really support Nintendo. Even the remakes for DS sell like crazy, but what does Nintendo get? Half assed Final Chocobo Swords Quest spinoffs.
Two reasons I can think of:
1. There's a long term agreement with Sony
2. They are still so deeply pissed off, Yamauchi must have said something unspeakably insulting about their mom.
Luckily I don't care for SE's bazillion of turn based fantasy kitsch games, but from a strategic point of view, it's annoying.
