Please. Please just stop. It's the Holiday season. Presenting a beta during the months of Thanksgiving and Christmas is not a wise idea. It wouldn't work so well when everyone is wanting to be with their family. And as someone who played both the Horde and the Alliance zones at Blizzcon - the beta (while yes - it probably has progressed much farther in the past weeks) is not 100% ready for beta at this point. I found plenty of bugs - some of which making me abandon quests - others making my character not work correctly. If anything I believe it is in a Alpha stage, and that by the END of January we will have a beta. I say END of January because who knows what complications will arise - and maybe they will want to add new models in before releasing the beta.
Overall - just wait. Good things come to those who wait - and if you guys want them to rush it, I guarantee it won't be as good as it can be.
