I would LOVE to see KH3 go multi.
but for Wii addition, I would like to see some true innovation, no more "instead of press Attack button, you wiggle your Wiimote" garbage.
I'd HATE for KH3 to be multi and I'm 100% positive it won't be and will be Wii exclusive.
I've already said the CT For the Wii is different from the CT for the PS3/360/PC. Unless they want to gimp games I don't think they'll do that. Besides, when was the last time SE has gimped a game? Honestly, a big game like KH3 won't involve fooling around.
