That's what I had thought. Anyway according to that article there will be a few Guitar Hero games this year, I'd expect one of them to be the actual GH4.
I just hope its compatible with the Rock Band controller, otherwise im gunna have to get the crappy PS2 version.
Yeah... why not Led Zeppelin to help relaunch thier career. Aerosmith is cool... but there are better bands, and thier guitar isnt that legendary like all the other bands on other games. By the way... this is not GH 4.
