The sequel is officially making its way to the stage this September and plans to "elevate the music game experience to the next level."
They address DLC fears too announcing the "cross title compatibility". The PS3 as well as any other versions are due out a little later in the year.
There's no need to panic about your DLC for Rock Band because all those tracks you may have got your digital hands on can be used in Rock Band 2, and will keep working for both. No specifics on what Harmonix have plastered over the discs but it's possible the set list could number in the hundreds.
"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."
New and updated peripherals are being included in bundle packs but all your Rock Band stuff will work just fine so no need to raid the trust fund.
On why Rock Band 2 will be strumming recklessly on Xbox360 first a Harmonix rep said: "Microsoft has been a great partner throughout the launch of Rock Band in the last year and their continued support is instrumental in supporting the more advanced features and cross title compatibility we will have in Rock Band 2."
"Of course, our goal is to make Rock Band 2 accessible to all and we look forward to bringing Rock Band 2 to all relevant platforms later this year."
Expect more from this year's E3 event.
