The Wii lineup isn't bad. He was asking for big hits, the Wii is getting tons of great games besides the ones named like Overlord, Muramasa, Little Kings Story, The Conduit, Arc Rise Fantasia, Kizuna, Valhalla Knights, Takt of Magic, EA's Grand Slam Tennis, Cursed Mountain, Silent Hill, Spyborgs, Excitebots, Rabbids Go Home, Punch-Out, Sin and Punishment 2, EA Active and many, many others along with a bigger number of multipatform games like Dirt 2, Formula 1, EA sports brand, tons of GH's and Rock Bands, movie games like GI Joe and Wolverine, possibly Modern Warfare 2, some other rumored stuff and a huge line-up of excellent downloadable games.
The thing is there's not a big hit included in those I listed. Will be a pretty good year, but ironically thanks to 3rd parties rather than Nintendo itself at least going by the current lineup.
