In a truly shocking turn of events, Wired is reporting that Rock Band instruments will be compatible with Guitar Hero: World Tour. You might be wondering how this is possible, since the RB drums have one less input than the upcoming GH:WT drums. Director Brian Bright says that the tracks will be "compressed" if a RB drum set is detected. All in all, this is great news for fans who are running out of space for more instruments. If rival games like Rock Band and Guitar Hero can play nice with each other, surely world peace is not too far behind. Perhaps soon, we'll even see dogs and cats living together!
