We've been waiting for Harmonix to deliver the promised Xbox 360 wireless Rock Band guitar controller for a while now, and it looks the company is stealthily getting them out there. Pre-orders have been trickling out for about a week, and alert reader Greg just sent us these shots of the controller in the wild at his local Best Buy. Oddly, he says the in-store price is $79.99 while the BestBuy.com price is $59.99, so if you're looking to cut the cord, you might want to save some cash and order online. Oh, and remember -- this bad boy doesn't work with Guitar Hero, so don't say we didn't warn you. One more shot after the break.
