While you're playing it on your Wii. The Wii you bought the game for. Pics on IGN show that the kit comes with an improved spring on the drum pedal, but then since every version of the game shipping these days comes with them, may I remind you of my first point. That it's just like every other Rock Band drum kit you've ever seen. Just white!
