Zarhym commented in Twitter there might be plans to let beta testers play the Mogu’shan Palace and Shado-pan Monastery (both 5-player dungeons) in the next World of Warcraft: Mists of Pandaria beta push. A new zone will be available, and the level cap will be raised at level 88.
The Shado-pan Monastery is located in the Kun-Lai Summit zone, and the Mogu’shan Palace is located in the Vale of Eternal Blossoms zone. Check out our recent Mists of Pandaria Maps screenshots.
