Details are still mondo sketchy at this point, but the FCC just delivered satellite radio fans a new present today: XM's "X2G-100" XM2go portable. Looks vaguely like a Pioneer Inno from the rear and we're hoping it's not some upgrade we're getting ourselves all worked up over, but if it was it'd likely not be filed by XM. Now watch as XM goes about its own business until one day it "suddenly" announces this mysterious device.

Update: Steve T writes to let us know it might just be Audiovox's XM2go device. Could be, but we still don't know for sure if this is going to be that same device which will provide "the ultimate music experience."
