As I've said before.......Rock Band is very much next-gen, and has a few issues before it to run on the Wii.
Rock Band, with all of its goodness is a memory hog - Wii owners, the majority would get a rather gimped version of the game like the PS2 version - which has no avatar functionality, no online MP, no DLC.
And that's the key of Rock Band - DLC. With a very limited built-in flash card (512mb) the DLC would be severely limited, or non existant for Wii owners. They could always upgrade their systems with bigger drives which would be important - but would alienate core users.
So its kind of a "darned if you do darned if you don't" situation with Harmonix and Rock Band - either give no DLC, or give huge-sized DLC (songs are 30mb-60mb each) and render Wii flash drives useless.
Hopefully EA can indeed sort this out, as Rock Band would be very profitable.
Back from the dead, I'm afraid.
