Good news, plastic rockers -- Activision announced at E3 today that its upcoming Guitar Hero: World Tour game will work with Rock Band's controllers, including the drumkit, and that Guitar Hero: Aerosmith on Xbox 360 has received an update that "should" make the game compatible with Harmonix's axes. Nothing too wild on the Aerosmith tip, as the guitars should just work now (finally!), but Activision's had to do some work to make World Tour play nice: the game is designed for a five-pad drumkit, but it'll compress down to four to work with Rock Band's set. See? Friends all around. Is that so hard, guys?
