I would love to visit Black Marsh, especially the capitol of Helstrom. We might be seeing it in ESO's upcoming Murkmire zone, but I'm not sure.

But as to TES VI, the most likely province is Hammerfell, or maybe what some guy on Reddit suggested a few months ago, a combination of sections of Valenwood, Cyrodiil, Hammerfell and the Summerset Isles: http://i.imgur.com/J97LrY0.jpg

While it's more likely, I would by far prefer to visit Black Marsh. Mainly because it'll be unusual. One thing I loved about Morrowind was the other-worldly feel to it, mainly due to not being a human province. I'm hoping a game set in Black Marsh could capture the same feeling.
