Earlier today, the trailer for the new Skyrim DLC was released on YouTube. I won't bore you with the details, take a look for yourself instead:
The DLC is about the first Dragonborn, a dragon priest who devoured dragons, and who ruled Solstheim back in the days - and now he seeks to return. So, what can we expect to see in this DLC? Well, there are a few things:
The island of Solstheim, dragon riding, new creatures (Riekling, Scrib, Netch, Boar, Benthic Lurker, Ballista Centurion), new armor (Bear Armor, Bonemold, Chitin, Nordic and Stalhrim), an Arena, Spears, a Telvanni tower, and of course; giant mushrooms!
The island of Solstheim is according to the lore, primarily inhabited by Nords and Dunmer (who fled Vvardenfell), so those races will most likely be the essential races of this DLC. The village seen in the trailer seem to be a mix of Nord and Dunmer Redoran culture, which might suggest the Redoran have most presence of the (former) great houses of Vvardenfell, though this is all simply speculation at this moment. To those who are thinking "but I have already been to Solstheim, why should I go there again?" (who thinks that anyway?), remember that this is 200+ years after the events of Morrowind, so a lot have likely changed.
The DLC also seem to include a lot of new models, which will come in handy for any modding projects, like the Beyond Skyrim project, who aims to create the whole world of Tamriel in the Skyrim engine.
Dragonborn will be available for download for 1600 Microsoft Points on Xbox LIVE on December 4. Any release date for PlayStation 3 or PC has not been announced, but since Bethesda Softworks' Xbox exclusivity deal with Microsoft should be ended by now, it should be around the same date (unless a new deal is in motion).
