As a general rule, GameStop is perfect for coming up with good video game rumors. In fact, it's practically a rumor generator. That said, this particular product listing is very interesting. Just yesterday, it was announced that Harmonix was working with MTV and Electronic Arts to create Rock Band (think Guitar Hero with a full band). Now we see this listing on GameStop for a wireless guitar controller ($80? Ouch). We have no way of knowing if the controller would be specifically for Rock Band, but we would certainly hope not, considering Guitar Hero II has yet to be blessed with such a peripheral for the Xbox 360. The listing has a ship date of November 1st of this year. Do we really have to wait that long to get some wireless guitar action?
And that's when the GameStop rumor train comes full circle, as apparently you can already buy 360 wireless guitars used (they're even back ordered). We'll just have to wait and see how accurate the Rock Band guitar listing turns out to be. Keep your fingers crossed.
