Drums Coming to Guitar Hero IV?

Looks like Rock Band is rattling some nerves over at Activision, maker of Guitar Hero. According to Bobby Kotick, Activision’s CEO, the fourth iteration of the seminal music game will include other instruments, even drums. No word on what the kit will look like, but we’re hoping for an improved kick pedal at the very least. And what the hell will they call the game now—Instrument Hero?
