Came out a few days ago with potential hints at future stuff. ICC, Pandaria and Dark Portal.

Based on the schedule they want to do, we should be expecting a adventure in a couple months and that there will be one more expansion before the end of the year of the kraken. Then a new expansion for the new year after that. If it's ICC then we can guess future expansions based off the other two. Pandaria/Draenor expac?
Or it could be nothing. But it's fun to speculate.
