April 3, 2007 - Yesterday, Harmonix owner MTV and publisher EA held a conference call with the press to announce http://ps3.ign.com/objects/897/897524.html. During the Q&A session, we misunderstood Harmonix CEO Alex Rigopulos and thought he stated that the guitar from Guitar Hero II on Xbox 360 would not work with Rock Band.
However, today on the http://www.rockbandgame.com/index.php?do=/public/forum/posts/id_58/, developer Jason Booth pointed out our mistake. Apparently the guitar will work with Rock Band. PlayStation 3 owners will, however, need to purchase a new guitar unless Harmonix releases an adapter.
