WiiWare is basically Wii's version of Xbox Live Arcade and the PlayStation Store. I don't see why Rock Band Blitz isn't going to be available for this. I'm sure many Wii owners (such as myself) would love to see this happen. It comes out in the summer, so if enough people want this to happen, Harmonix will hopefully see the demand by then and release Rock Band Blitz as download for the Wii!
