Game Informer has a picture of the drum kit for the upcoming Guitar Hero IV. The immediate, unanswered question is whether or not the game will work with Rock Band’s hardware, and vice-versa. Business-wise it doesn’t make sense to me to force customers either to choose between platforms or to fill up their houses with 6-8 plastic instruments. I can see lots of parents and spouses denying the purchase of yet another set of plastic drums.
