World of Warcraft: Mists of Pandaria Announced and Screens/Trailer

Fourth World of Warcraft expansion reintroduces the mysterious pandaren race to Azeroth
Blizzard Entertainment today announced the development of Mists of Pandaria, the fourth expansion to World of Warcraft that lifts the fog of mystery surrounding a long-lost continent that has been newly rediscovered following the events of World of Warcraft: Cataclysm. The new expansion reintroduces as a playable race the elusive pandaren, originally seen in Blizzard's real-time strategy game Warcraft III, and adds a brand-new player class: the martial-arts-focused Monk. While exploring the mysteries of an exotic new land and advancing to the new level cap of 90, players will experience a range of new content and game features, including new quests and dungeons, group scenarios and "challenge" modes, pet battles, and more. Check full story for details - a batch of screenshots has been added in our gallery.
Update: a trailer is now locally mirrored (thanks: Blues).
