Well for some reason NA software sales still haven't been updated past launch week for GH:A but if NPD is to be believed the Wii beat out other SKUs. Interesting...
Well to be fair, this game isn't in Japan so if you take out the Japanese userbases then the Wii is up on the 360 22-19. Still winning but hardly "PS2 domination".
Analysis of a single week of SW sales on a casual title FTW!
