Um, dunno what part? If the engine can work on the Wii, it still can work on it. Heck, I think Crystl Bearers used it, and that wasn't even puching the Wii. Or was it something else you are replying to?
oh sorry, something else. the part of this thread i had previously responded to and skimmed over today was about where KH3 lands. wii exclusive, ps3 exclusive, HD exclusive, ect..
