While the axe that comes with Guitar Hero: Aerosmith is pretty sweet, if you were hoping to just get the game and use your Rock Band guitar, you're out of luck. Despite rumors that Activision had opened its doors to the Harmonix-made Rock Band guitar controllers, early users of Guitar Hero: Aerosmith are reporting that the Xbox 360 version game isn't being so friendly after all. The sad message: "An unsupported guitar peripheral has been detected. Connect either a Guitar Hero guitar or Xbox 360 controller and press START to continue." It's like they never even knew each other.
