[BENELLISBE2]

1. when does rockband come out for Wii
2. what is the replacement disc for?

[Spud]

1. June 22nd last time I checked
2. GH3

[GreatGonzales106]

1. Sunday, I believe

2. stereo sound instead of mono (probably other things, too, but that's the main reason) with the GH3 disc

It also locks up less and has better load times.
