Wish I had seen this topic sooner. Last week Harmonix, the creators of Rock Back and Guitar Hero, had a survey of what bands people would like to have their own game. They had a short list to choose from. Led Zep and Rolling Stones were among the choices out of a list of about 5, if memory serves. A second question was a write in, asking what other band that wasn't on the list should get their own Rock Band game. I, of course, picked STP.
If nothing else, I'd like to see them get whole albums released as DLC, like other bands have.
