From what I have heard on mmo-champion.com, apparently GW2 beta invites are being sent out. So, for those that signed up, be sure to check your email. But, you have to sign an NDA contract, which means you can't tell us if you got in, which would kill me.
I guess, first rule of GW2 Beta is you don't talk about GW2 Beta? I seriously hope that I get in, so I can see if my computer can run the game or not. *cross fingers*
