At D.I.C.E 2012, Todd Howard from Bethesda Game Studios kicked off the show with his keynote.
The developers at Bethesda Game Studios had a chance of doing whatever they wanted to the game after it was finished and put it in the game, but they didn't. This was, as they like to call it, Skyrim Game Jam. Todd Howard said that all the things they had could come with the DLC, or as a free pack. Although, they are not sure.
Here is the video they've showed at D.I.C.E 2012 of their mods: http://www.youtube.com/watch?v=8SE5owAIPmk
