SSX Blur and Sonic are the biggest releases for Wii until Super Paper Mario. Sonic has traditionally sold better on GC than other platforms. I'm inclined to agree with Zsidane when it comes to how well Sonic will sell on Wii. Now SSX Blur is the one I'm not sure about sales wise. BTW Starcraft Maniac, Sonic hasn't been released in Japan as of yet. I think it comes out on March 14th in Japan.
