^2010 looks amazing.
But yeah, the problem is no one wants to invest in a good Wii game until theres a proven market for them. When those markets have opened companies have filled the gap - Wii has lots of preteen / fitness / music games no other console has. They've got to open up sooner or later though :/.
The only real exception is Red Steel, but Ubisoft seem to have ballsed that up. I've no idea how a Wii game can take 3 years to make a sequel for, I'm kind of worried it's been a bit too long now though, and most people will have forgotten about it.
