The exception being the new Orsinium being that it gets independence and won't be a part of Hammerfell in years to come.
If they are having a quest on the Falmer and a new High King then I hope we go to either Atmora or High Rock. High Rock is so similar in terrain that I doubt very much we'll be visiting there in the near future so it makes good pickings as a location for an add-on the Skyrim. Plus Breton are the human opposite to Nords = magic users. It'll tie in nicely with the Reach
