I did some googling this morning, (there's only so much to read about the Lions vs Matty Flynn and the Pack).
I stumbled on this video promo from Nike that was released in September. It's narrated by Micheal Irvin who says there is "epic change" coming in 2012. It's a very well done video, which in typical Nike fashion doesn't give much away. However, at the end of the video, time stamp 1:03, you'll see what appears to sneak peak of the Raiders jersey. I'm assuming this based on the skull at the base of the collar. And yes, they look totally awesome.
