While the technical specifics of how exactly it would work escaped me, I still held onto hope. Hope that, by some miracle, I might be able to use my PS2 guitar controller with my Xbox 360, given I had a USB to PS2 controller adapter (or magical pixie dust). I mean, the 360 guitar controller is a USB controller, right? It's gotta work!
Yeah, not so much. Don't waste time like I did. Spend it trying to beat my high scores, instead.
With that in mind, it pains me to bring you this news. If you plan to rock out with a friend, you might have to start selling drugs again just to fund it. And oh yeah, Electronic Art's Rock Band is going to have a wireless 360 guitar, apparently. Ouch.
