FYI for anyone who doesn't know... the NDA is PARTIALLY lifted. You can discuss and post screenshots, but NO video or audio.
I only write the reminder cause I've seen a few beta videos pop up already. It's a damn shame people either don't read the rules or think they're above it. I've also seen a "screenshot slideshow" video on youtube. Not sure where that lies in the NDA but I wouldn't risk even that.
