Strumming from the previous post which unveiled Rock Band's guitar controller, two other peripherals have now also been thrown into the PS3/360 center stage. From 360post, this scan from a Game Informer magazine shows the drum set and microphone for Harmonix's game.

Now, about the microphone peripheral, I've squinted at the scan for quite a while to read the text, and it seems that, while Harmonix will release their own branded mic, other third-party USB mics could be supported. This however won't encompass the Xbox 360 wireless headset.

As for the drum set, it seems that (unless my straining eyes deceive me) the leg stands are collapsible, which makes the whole set easy to store. The actual drums though are fixed in place and don't seem to be movable to whatever position/angle you're most comfortable with.

Do note that both the drum set and and microphone seen in the scan are concept prototypes but is reported as "unlikely to change drastically before release."
