I read somewhere that they said that their dlc would take place after the mq was completed a la fallout 3. This interests me a lot since that would mean that they're expecting experienced players only and that would mean some ramped up bad guys and a higher level of loot. Hopefully it also means some more complex quests (also like FO3). While some of Fallout's dlc felt tacked on, with a bit of luck they will be lore heavy extensions of the story (epilogues rather than tangents) and they'll develop the tale of Skyrim. We'll see.
