Christie posts: "Okay, starting on Tides of War, the Jaina (Proudmoore!) book. Am thinking if I work this right... I won't have to work weekends this time. Woot!"
There is a lot of speculation going on about the next expansion, including the filing of a trademark for Mists of Pandaria, as well as Chris Metzen revealing the earth-shattering Jaina book at Comic Con last month. While Tides of War is admittedly a working title, it signals a strong naval theme that links up well with an island expansion, the island of Pandaria, and a generally water-y world we're looking at. This is all still speculation, of course.
