Rumor: Guitar Hero hardware won't work with Rock Band

I don’t play Guitar Hero because I suck at it so I’m not sure why this is even such a big deal, but apparently it is so I’m letting you all know. There was some speculation earlier that axes from GH 1 and 2 would be compatible on Rock Band, but I heard that Harmonix isn’t down with that. In fact, they pretty much told he/she/it that it’s not going to happen. Why that would matter to anyone, I’m not sure. I don’t play the game so that’s probably why, right?
