This is from the IGN Guitar Hero 3 review for PS3:
Perhaps the best addition is the new Les Paul wireless controller. This is by far the best guitar peripheral yet. It's so good, in fact, that it actually makes the game a great deal more enjoyable than when you play it with anything else. This is the guitar to own and since it works with Guitar Hero 2 on Xbox 360, it makes the purchase a no brainer for anybody that has even a passing interest in guitar rhythm games. The only downside to it is that it won't work with the PS2 versions of Guitar Hero 1 or 2 when you put them in your PS3.
Am I not understanding this correctly. It sounds like the PS3 guitar works for the GH2 on Xbox 360.
