It looks like a new site is up at www.notfornoobs.com. I snagged a screenshot of the "secret symbol" that shows up, a logo for the Razer brand of peripherals.  I have to admit, it's not the best I've seen- putting Microsoft logos into teaser programs is a no-no in my opinion.  But is this a tie-in with the soon to be smash-hit movie, "Snakes on a Plane"?  Gizmodo thinks it's a new game hardware product announcement.  

Even if I knew, I couldn't say. 
We'll just have to wait and see. ;)

Final Update: Early in the day I posted this, I had some concerns about authenticity which have since been cleared up – looking forward to when we all learn more <g>.
