I'm 95% sure it won't be the Dwemer returning, this has been one of the biggest mystery in the series since the very begining and if they revealed it the series would lose one of it's major set pieces, it'd pretty much be the Swan song, that's something that if they ever do reveal it'll be at the end.

The Thalmor does seem very likely considering that even in Oblivion there was talk of trouble with the high elves and now they are just kind of a presence, waiting on the edge of the world, poised to strike or be struck.

After playing through Dawnguard I'm thinking it'll be something to do with the Falmer though, I've seen a few merchant carts and groups of travelers that look like they were ambushed by the Falmer, just bodies with falmer arrows in them and falmer ears lying around the scene. My first thought was that the Falmer were getting bolder and maybe will try to invade the surface soon. Though this could just as well be another way to bring the world to life, either way I thought it was neat.

I'm personally hoping the next expansion returns to Morrowind/Vvardenfell, maybe brings back spears and throwing weapons. Morrowind is still my favorite entry into the series just because the world was so interesting and there was so much variety to it, more legendary weapons and cool treasures to find, I put several hundred hours into morrowind and reinstall it probably once a year and while the combat and the graphics haven't aged well the rest of the game still impresses.
