Alot of interesting stuff is coming as far as platformers go for Wii. Particularly with regards to drawing as a new mechanic for platformers. It will be in Epic Mickey and a number of the WiiWare platformers.
Beyond that there is the Vitality Sensor. We don't know what it will do, but if I worked at EA or THQ or Nintendo, I'd be working on a game that uses truth/lying as a play mechanic not some expansion of a horror or a fitness game. Can you imagine how much fun a multiplayer game centered on lying would be? "Do you like this game" if you say "no" you could get a game over....crazy shit like that." How about "is my girlfriend hotter than his" and just have everyone answer...the lie/vitality/pulse detector. Seems like a blast to me.
Traditional stuff is coming to Wii as well. Sky Crawlers, Monster Hunter 3, Samurai Warriors 3 - all that stuff will do ok in the west and establish a base for a handfull of successors.
With X360/PS3 you probably had the best years for new genres/bringing old genres onto the systems in 2007-2009. For Wii, I just feel like a lot of stuff that should have been on the system/ should have been thought of earlier is actually coming in 2010.
