I really think there is a strong possibility it spans the whole of Tamriel, for the first time ever, we have a console generation (amost here) and a computer generation (been here) that can actually run the whole place without exploding.

Thats one outcome I think is likely.

My other possibility is Highrock, Hammerfell and the Somerset Islands, or Valenwood, Elsweyr and the Summerset Islands, as all of those by themselves are too small.
