There was a recent thread on the next TES game being all of Tamriel, which I think is a bit too ambitious and likely very very difficult.
I was wondering, though, if in the next one we might be able to see 2 or possibly 3 provinces in one game that are connected.
Personally I'd like to see Valenwood and Elsweyr in one game... size of which looks similar to Skyrim.

Thoughts? How big do you think is "too big" for the next TES?
