User blog comment:Rakoslod86/Skyrim: DLC That Unlocks a Province of Tamriel./@comment-5469467-20130112065111

I would like to explore all of Tamriel as well, but preferably on a game-by-game basis. Adding an entire province is way too much for DLC, mostly because it would be a massive addon (not to mention expensive, presumably) but also because Skyrim is meant to be about exactly that: the province of Skyrim, it's inhabitants and the adventures the player will have there. No, instead I think Bethesda should continue the practice of having a new province in every game. That way, we can explore all of Tamriel (and move onto the rest of Nirn) in detail.

As for TESO, I don't know if the provinces will be that impressive. I suspect they'll be smaller and less lively than in a typical singleplayer game, but still interesting enough (especially places we haven't been yet).
