Blizzard has opened up beta signups today for Mists of Pandaria and stated that beta testing is “very close“. For those of you with a Battle.net account, all you need to do is login and check-mark the opt-in option for Mists of Pandaria.
The beta will have no non-disclosure agreement (NDA) so all participants will be able to talk and post images and videos about the game. Players who are selected will receive an email from Blizzard with instructions on how to download the game.
WoW Annual Pass holders will get special treatment, the longer your annual pass has been active, the sooner your chance to be invited to the beta and all annual pass holders will eventually receive an invite. This means if you are not an annual pass holder, your chances will be slim, as Blizzard has stated additional invites will be only sent out if there is a need for more testers.
Currently there is no end-date for the beta.
