Good news for Rock Band and Guitar Hero fans. Microsoft and Sony have both confirmed that all the plastic instruments from Rock Band, Guitar Hero: World Tour, and Rock Revolution(who?) will all be compatible with each game. For example we get to use the Guitar Hero drums for Rock Band and Rock Revolution. Sony has stated that the microphones for each of these games will work with their Sing Star series. Microsoft did not say anything about the microphones being compatible with their karaoke game LIPS.
As for me I am very pleased with Microsoft and Sony for making sure the games instruments are compatible. I really don't have room for 2 sets of plastic instruments. Now I can just buy the set of instruments for GH:WT and be able to use them with Rock Band.
