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.
The previous Kingdom Hearts games has been exclusive to the PS2 with a Gameboy version thrown in. The developers have already confirmed the game will be coming for the next gen consoles.
Not a whole lot of info in that rumor. There isn't much to say on it, but it's worth noting. Also keep in mind the "next Kingdom Hearts" is the spinoff to be announced at TGS.
