"The Friends and Family milestone has come to a close and in just a few short hours we plan to open the Cataclysm beta to the general public. As many of you are aware, it’s taken a lot of hard work and perseverance to reach this point. This is always a big moment for us in the development cycle, and we couldn’t have gotten here without everyone’s help and support. The feedback and reports coming from you, and all of our friends and family testers has been paramount in reaching this moment, and we thank everyone for their commitment to making this expansion happen"
From a post in the FnF Alpha forums. Not by a blue but someone stating this is coming from a friend that works at blizzard.
