Annual pass owners get in regardless.
Users who fancy getting into the upcoming World of Warcraft: Mists of Pandaria beta can take a look at the latest beta FAQ that Blizzard has revealed, explaining how to participate in the testing period.
Those who have a Battle.net account with at least one Blizzard title attached can sign up for the beta using the beta profile page. After this they will need to wait for an acceptance email.
Users with an annual World of Warcraft pass, however, will automatically be invited to the beta, however they may be forced to wait as invites will be staggered in waves.
Recently the firm released four new trailers that give players a glimpse of what to expect in the Mists of Pandaria expansion.
Mists of Pandaria has no official release date but is expected sometime before summer of this year.
