I would personally like to. I also think that the odds of them appearing as DLC are high as they would make perfect DLC settings.

Anything that expands already on the existing content with the same quality and faithfulness to the Elder Scrolls series would be super awesome in my opinion, I don't think a new continent straight up would work best though, once all the land on the current continent is used then I'd be interested in them expanding it further with others.

Either way, more content is more win IMO
