Until I hear something official, I'm not really biting on anything about a Rock Band 2. It's been this giant debate of GH:WT vs RB2 on the Harmonix forums for months now, and it's really become quite annoying, lol. I think RB2 could be a good idea for some changes to online play and world tour, but I don't know if they necessarily need to release a brand new game to accomplish that... seems like it may be possible with a patch. I'd be a little disappointed if they rushed RB2 out just to try and compete with GH:WT. Since Harmonix left the development process of GH (post GH2), a lot of people have been very unhappy with Guitar Hero, and I don't think Harmonix and EA have anything major to worry about at this current time (maybe in the future). When RB2 comes out, I want it to be like GH to GH2 was, not like GH2 to GH3 was.
