Harmonix announces Rock Band II
By Phil May - 15 May 08
You're officially going to need a bigger garage...!
Harmonix has announced that Rock Band is about to get a sequel, and a "fully fledged sequel in line with the sort of sequel you'd expect from other big game names" sayeth Harmonix. As yet they're playing things quite close to their chest with no massive announcement about new or updated peripherals (it's about time someone gave you something wilder, guitar wise, than just a Fender or Gibson knock off, don't you think?)
The sequel's scheduled for 2009 and will feature the same downloadable content sharing dynamic as the first title. More details when we get 'em.
