A generous reader of the latest Game Informer magazine has scanned an image of the drum-kit to be included in Guitar Hero IV.
As you can see, the main difference from the Rock Band kit is that the yellow and orange drums have been turned into two wedge-shaped pieces elevated above the others.
Cool as it looks, we still don't have the most important piece of information about the kit: If it will be compatible with Rock Band, or if RB's kit will work with Guitar Hero IV. We like fake instruments as much as the next nerd, but two fake drum kits may just be more than our dens, living rooms and dignity can withstand.
