According to report from X3F, Guitar Hero IV (World Tour) will work with Rock Band drum and guitar for Xbox 360 at least.

So they saw that they can't compete with Rock Band 2, decided at least they could sell stand alone game to Rock Band owner. Smart move on their part because I would not touch IV unless it work with plastic instruments I already have.
