WTF is a stage kit you ask? Details are sketchy at this point, but it seems the makers of Rock Band are releasing an add-on pack to make your band feel more legit. According to a pre-order page on GameStop, this will transform your average game play into an "interactive light and smoke stage show" (the site has since removed the image and description). You'll have plenty of time to save up those dollars, as this accessory isn't released until June. Worthless? Highly likely.
