User blog comment:Timeoin/Is 'Redguard' the next Skyrim DLC?/@comment-114.76.152.141-20130107134137

The last Skyrim DLC most likely to come out would be a High King DLC where your decisions from the Civil War campaign come into effect to decide the new High King of Skyrim whilst defending Skyrim from The Aldmeri Dominion.

That being said, That DLC gives the oppurtunity to travel to Cyrodill to infiltrate to Elf infested Imperial City, So that might the reasoning behind the White Gold Tower being visible.

Another DLC that might come out before High King is an Oblivion DLC where you can visit New Sheoth, Sheogorath himself kind of foreshadowed this when he said 'If you find yourself in New Sheoth be sure to stop by'
