Im all for rap star, 2 turn tables and a mic, but it should be seperate, along with country and techno and anything else not rock. If I have to play through garth brooks or brittney spears to reach the next city ill be pissed.
No I don't think they are going to add any more cities. Anything they add would be strictly for download content. I think the only thing they could add game wise would be the ability to complete more achievements.
