Guess we won't have to wait for Pete Hines now. Believe it or not, the information for the upcoming DLC for Skyrim has been sitting under our noses ever since the last patch (1.5.26). However thanks to Raestloz (on the official Beth forums) who had been digging through the PC patch files had found individual animation files belonging to the first DLC for the game.
(Possible Spoilers) Among the new things you can expect in the 1st DLC are Snow Elves (aka the now Falmer), crossbows, vampire feeding animations (you might remember it from the Game Jam), and other things that cannot be figured out due to the file names. The Snow Elf entries indicate that the new DLC will revolve around or have something to do with the Snow Prince and his ascension.

If the Falmer are involved I have to wonder about the Dwemer and what sort of role vampires may play (unless that's just a feature update and they play no role).
