* UPDATE: Leaked photos here too. There are 22 total images, including the reveal of that teased female Pandaren silouette.
Apparently, while Gamesradar was preparing their new Mists of Pandaria Press Event videos for release this coming Monday, they inadvertently posted them online (either that or they thought no one would notice.)
These videos don't contain a ton of new information, but they do reveal the new dungeons as well as many of the races, and previously unseen areas. This is just some the footage that every fansite out there will all be showing off (identically along with the same zone/dungeon details). More to read, less to watch come March 19. :)
