I doubt I'm the only person who would love for Kingdom Hearts III to be released on Wii.
I'm not going to diss Sony, but... sales for the PS3 aren't the best. Would Square consider releasing KH3 on multiple platforms?
As long as they don't try to "revolutionize" the game with motion controls, or throw Mario in there, I'd be really happy if they released it on multiple consoles.
After all, they've released Chain of Memories for the Game Boy Advance and Kingdom Hearts: 258/2 Days is coming out for the Nintendo DS
