Now, considering how unscientific this methodology is, we're pretty sure our margin of error is in excess of 5%. Even if we were to consider the information accurate, we're still at a deadlock. Activision isn't talking (really, we've asked for a comment several times), so we're going to go with this: there are multiple versions of the Rock Band Stratocaster and some will work with Guitar Hero: Aerosmith and some won't. Really, that's the best we can come up with. Of course, this would be a whole lot easier if Activision would just agree to play nicely.
