Is Bethesda Teasing New Skyrim DLC?

Bethesda is teasing a new trailer set to arrive on Monday, November 5th. On the Bethesda Game Studios Twitter account, Bethesda posted a mysterious image (seen below) along with the note “Full Trailer on 11/5.”

The only Bethesda Game Studios project that’s been formally announced is Skyrim, strongly suggesting that this announcement will be related to new downloadable content (while Bethesda recently published Dishonored and will publish The Elder Scrolls Online in 2013, those games are developed by Arkane and ZeniMax Online, respectively). Earlier this month, source code in Skyrim’s 1.8 update pointed to new content called Dragonborn that would allow players to ride dragons. If that proves true, we could see the trailer for Dragonborn as soon as next week.
