Seriously, what are you waiting for? Head on over to the Microsoft Connect page, sign in, and register so you can enjoy this Fall's Xbox LIVE Preview Program, which it so happens, changes a lot of things on the Xbox 360 Dashboard. Like a new (hopefully awesome) "Metro" style interface, lots and lots of Kinect support, including Bing support, better Facebook integration, and the much anticipated Cloud Storage! Not so sure about YouTube support, but they could add that feature later on during the Preview Program.
I signed up earlier today, so you, too, should also sign up...like now before time runs out!
