Rock Band for iPhone

The creators of Rock Band are currently working with iPhone to make their first iPhone application ever.
Gamers are now going to be able to play Rock Band anywhere, anytime. Users will have to tap spots on their iPhone screen that will correspond to guitar, bass, drums, and vocal parts.
The list of songs that's going to be included is said to be pretty good too.
What more could a gamer ask for?
