EA have today revealed to IGN that Rock Band 2 will be released worldwide on Xbox 360 in September, with other platforms seeing the release later this year.

Harmonix commented to IGN "As successful as the original Rock Band continues to be, we’ve now had the benefit of the last eight months to listen to our fans’ requests and to build upon that foundation," said Alex Rigopulos, co-founder and CEO of Harmonix. "Rock Band 2 is a second-generation band game that will elevate the music game experience to the next level."

Harmonix also revealed that all downloadable content including that from the original Rock Band will work with the new game, so you can continue to play the original game and expand it using the same downloadable content which is released for Rock Band 2. New instruments will also be released although the old instruments will also be compatiable.
