What has been confirmed to be coming into the game with this DLC? Aside from the trailer, I've not seen any information about this DLC, I haven't been keeping up with skyrim lately due to all the other new games coming out. And I'm having trouble finding anything credible.

Some new screenshots and vague descriptions: http://www.elderscrolls.com/skyrim/add-ons/

i am surprised that Bethesda had not done one single interview with some gaming site to promote and talk about upcoming dlc like they did with DG

I think we will see some more information this coming week.

Exactly this, oh yeah, and not forgetting the perpetual "coming soon" for PS3

Raven rock? thought they ran out of money
