Quote From Emupedia.com which probaly got it somewhere else :PBlizzard announced today that the 3rd Exansion, scheduled for 2008, will feature Arthas, and Sylvanas as we've never seen them before. And will take the game to new heights! Players will be able to visit Northrend, a continent twice the size of Outlands, and battle some of the fiercest foes ever to be seen in the history of the game. This new expansion will certainly be a sellout, especially considering that the new content caters towards the younger part of the World of Warcraft players.
