Guitar Hero World?

I have been hearing allot of things about guitar hero world tour on what the modes are and feature they added on but what are some of band names that will be in the game? Also if you get guitar hero world tour what is the mode you are most exited about on the game?

Some of the confirmed bands are Van Halen, Linkin Park, Jimi Hendrix, Lenny Kravitz, System of a Down, Interpol..etc.

I'm most excited about the song creating feature, I think that'll be neat. You could probably find more info at wikipedia or scorehero.
