In all honesty, why not both? Why not have a game that takes place a little while after Skyrim, where you have to travel throughout Elsewyr, Black Marsh, Valenwood, and the southern part of Cyrodiil to lead a resistance against the Thalmor menace and lead the lands to freedom? Or, alternatively, join the Thalmor and take part in the systematic destruction of all life! Considering how much the Thalmor were hyped up in Skyrim, it would be a shame if the next game didn't capitalize on how much everyone hates them: the whole thing could be about rousing the people, ambushing Thalmor patrols and bases, and eventually leading an all-out rebellion to force them out of each province, backed up the Empire.
If I had to choose one, however, I guess I would pick Elsewyr. It seems like a more varied environment, what with the deserts, jungles, and grasslands. Plus, I love the Khajiit - they're just so odd.
