Just to get some stuff straight about the Kingdom hearts:
1) Combined characters from Disney movies and SQ-Enix games.
2) Disney only develops Nintendo games since end of 2006.
3) Disney has their own Nintendo exclusive dev studio.
4) Nintendo bought a new development studio for Square-Enix, which is making Wii exclusive titles.
5) SQ-Enix has the Kingdom hearts rights (Franchise name, development rights etc...)
6) Disney and SQ-Enix decide together on which platform the new Kingdom hearts will be released.
7) Disney helps in co-developing the Kingdom hearts games (Remembral: Disney ONLY develops for Nintendo since end of 2006... I thought the name of the development studio was 'black box studios' or something).
8) The hidden trailer on the end of Kingdom hearts 2 DOES NOT CONFIRM KINGDOM HEARTS 3 FOR PS3... Some people say the graphics are too complicated for Wii! But: The trailer could just be FMV... Just like with EVERY SQ-Enix game showing FMV's to show a part of new games. Or: Just to get people hyped for a new game... Just to make people curious and get hype up!...
I.e.g: All the facts point out in the direction of the game heading to Wii... And maybe a spin-off to PS3 or DS.
And: I see some people in this thread making the argument: Square-Enix is loyal to Sony. THAT IS BULLSHIT! Square-Enix was loyal to Nintendo in the NES-SNES days... No-one could believe they went to PS1 with FFVII! But they go where the money is! Nes-snes / PS1-PS2 / Wii.
