I'd rather have an easteregg quest where you teleport to the city of Daggerfall to free the city from a (new) ghost that prevents magic from working (and hence you can't fly over the city walls).
We could re-visit the shivering isles as some DLC in skyrim,i'd love to know whats been going on there for the last 200 years,Since your guy from oblivion would be dead,so how would the shivering isles be like then?
No way, lets do something we haven't done before.... or Solstheim, I actually wouldn't mind going back there one more time.
Akavir would be amazing but they would have to make it "TES VI: Akavir" to give it any real justice... there's just to much there it's like a less divided Tamriel. Atmora expansion pack sounds more likely with the return of falmer (snow elves) and much desired "Human" background/history lore.
Atmora is somewhat like Atlantis if you think about it. However it did not sink it just froze over, but.. why?...
With Morrowind being blown to hell and taken over by Argonians, I hope to see it again in Elder Scrolls: Black Marsh.
Anyway. I think everyone is pretty tired of daedra after Oblivion. ( not me ) If we do go anywhere in a expansion I hope it's Orsinium and the areas surrounding it. Preferably a little of High Rock and Hammerfell so we can visit both the Dragontail and Wrothgarian mountains. I vote that because I don't see Orcs getting their own "full game" since they don't have a province to call their own. As a expansion for Skyrim it would be perfect.
