but as someone said, the beta is still in works, us beta tester still got to test 3 more new zones that havn't been launched yet, and the paladin revamp hasn't been implemented yet
also Deepholm is still being tested and has alot of fixing todo
and some dungeons havn't been released for testing
also two finishing quests in hyjal and vashjir need to be fixed
also blizz plans todo alot more
so the estimated time for the beta to be complete ain't for awhile
and we gotta test the first raids of cata the ones you get to raid with when it launches
plus I believe theres more BG's that havn't been implemented like the battle for gilneas
