the fact that this stream is at an unusual date and time for them and considering it starts an hour before PSN updates, i am fairly certain the beta is getting shadowdropped. i am REALLY excited to see how it ends up (although i will only get to play in the weekend sadly).
I bet the beta drops next Tuesday (Christmas morning) and is free for everyone that preorders the full game. And the game will get an actual date too, of course.
