Various tipsters and sources from around the web are reporting that the WotLK Friends and Family Alpha is now over. Deathknight.info reports that Eyonix has posted the official notice on the closed alpha boards, thanking everyone for participating.
There is, of course, no date given for the start of the beta, he only says that the team is hard at work preparing it. All alpha testers will be invited back for the beta, and will even be allowed to keep their characters after a short lockout period to allow new testers to catch up.
A poster at Wotlkwiki.info claims to have information from an alpha tester who is a member of a developer's family. The source says that they believe that Blizzard is rushing to meet an arbitrary deadline, as the game doesn't seem ready for beta testing -- this part, at least, is a bit hard for me to believe, since Blizzard has always marched to the beat of their own drum when it comes to release dates and deadlines. They also predict that we may need to wait until August to see the beta actually begin.
Regardless, it looks like beta will be upon us swiftly -- or at least soon. If you haven't opted in, now is a good time to do so. Once you've done that, keep checking WoW Insider. We'll let you know what we know as soon as we know it.
