Chances are it will be set in Summerset Isle, even with TESO coming out in 2013. If they do decide to do it anywhere else, I'd guess Akavir would be the place to go...

If they did go through with doing it in Summerset Isle, my guess would be of course the usual ten playable races, everything would be heavily based around magic, given that the Thalmor are the most capable in magic of all ten races (usually considered to be, at least), and the magic system would drastically improve like nothing we've seen before. To top Skyrim, they'd have to bring in more than the usual Leather/Fur/Hide/Iron/Steel/Elven/Swarven/Scaled/Orcish/Ebony/Glass/Daedric sets of armor/weapons, so I'd imagine they expand on that a ton as well. Most likely the same type of story as always, etc. etc.

But, if they went with Akavir, they would have all the freedom in the world. They could bring back some (or all) Tamrielic races, along with all of the native races of Akavir. We don't (REALLY) know much about Akavir aside from what lore has told us, so they could do essentially whatever they wanted. The default weapons for most would be Katanas, I'd imagine, everything else (weapons/armor) would be their's to play around with. That's pretty much all I can think of off the top of my head... if they did actually decide to go to Akavir, that would be a whole new experience I think EVERYONE would enjoy.
