OMG!!! I'll sign up tomorrow.
When you sign up, do you download the game? If so, can anyone post some screenies?
We did not get a download for the game for signing up, and it is against the NDA rules to post screenshots or any other information about the game if you ARE selected for the BETA. When you sign up, I highly recommend reading through the NDA rules, these aren't the type of rules you can just click "accept" to without reading them. They are very specific, and you will be kicked out of the BETA if they find you breaking these rules. And yes, they will be watching for NDA breakers.
For example, if they find out you simply told someone you were selected into the BETA, they'll kick you out of it. As someone else mentioned, early non-SE press is almost always bad press. They're not going to risk it.
