They officially stated that you could use either the classic GC controller or the new Wii-Mote. The Wii-mote is still undeveloped in controls for this game ATM but they are working on putting together some extra motion sensitivity functions for the game. Even though most people would prefer to use the classic GC style gameplay there still are those, like myself and my friends, who are looking forward to this new style of gameplay.
Hope this cleared a few things up. Also they have not released any controls that are said to be used for the Wii-Mote and most likely won't for a while. There is said to be a fairly large sized anouncement sometime within this month. Please don't hold me to this because I am not 100% certain about this but most likely there will be.
P.S. I just registered and probably won't be on that much but feel free to e-mail me with questions, comments, or anything really.
