Why some Annual Passholders have yet to receive a beta invite
Previously we reported that all Annual Passholders had been sent their Mists of Pandaria beta invites. But many players have been complaining that they still hadn't received theirs. Blizzard responded to that today. Those who have purchased the pass after April 18 will get their invites in a future wave. There were also errors when sending the invites to some accounts, and Blizzard is attempting to resolve them.
If you haven't yet purchased an Annual Pass, you still have time to guarantee your spot in the beta by signing up for a year agreement (link) before the offer expires on April 30. Those taking advantage of the Annual Pass receive Diablo III for free, access to the Mists of Pandaria beta, and the exclusive Tyrael's Charger flying mount for your World of Warcraft characters.
So if you haven't received your beta invite yet, you will Soon™. No dates have been released for when the remaining invites will go out. In the meantime, you can read up on all of the MoP beta info here on WoW Insider. (No, it's not the same as being able to play the beta, but I'm just saying ...)
