Found on KH Insider:
"The latest rumor on the street is that, the wii is going to be getting some Kingdom Hearts loving from its creators. The first ever Kingdom Hearts game will be announced for the Wii at this years Tokyo Game show."
I don't want this to be true. I don't want a Wii right now. Besides, it'll probably end up on a handheld if it's a Kingdom Hearts 2.5.
