With all the incompatibility out there among Guitar Hero / Rock Band instruments, it's a real treat to see something like this. The Director of Publisher Relations at SCEA has posted an update that promises compatibility between instruments and software for upcoming titles; for instance, Guitar Hero: World Tour's guitars and drums will work with Rock Band 2 and Konami's Rock Revolution software, and Rock Band 2's guitar and drum set will work with Guitar Hero: World Tour and with Rock Revolution. Furthermore, the team is still "working hard to ensure compatibility between the Guitar Hero and Rock Band titles currently on the market," though we are told that an announcement on that could surface "shortly." Rock 'n roll harmony, baby.
