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.
It could be for super attacks, or or use swings for wide swipes with the blade (for when you are inevitably surrounded), while you just press triggger for regular attacks.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
Plus, just for the hell of it: Kelly Brook at the 2008 BAFTAs
