Hmmm...could be a smoke screen BUT if set in Tamriel it could be in Hammerfell (though we've been there in Daggerfall and TES: Redguard. I'd say Summerset Isles but that would only be redundant since we have the TESO version, Elsweyr's a maybe but that region can be explored fully in Online as well as Valenwood. I doubt its going to be Black Marsh. Also I'm taking High Rock off the table! We've been there in Daggerfall so there's no reason to go back there again, it'd be a waste of a franchise to backtrack now.
So in retrospective TES VI can either be in Hammerfell or possibly in Akavir. Those are my only guesses.
The only part of Elsweyr that can be visited in Online is the western half of it. If it's even half. Dune is available iirc, but that's about it. It might as well be eastern Valenwood. There's really not much there.
The spinoff games don't really count for much in terms of "pick a new province" and I'd wager the reason they stopped doing them was because no one played them.
As for Daggerfall, it wasn't the primary province. So Hammerfell is a pretty good possibility.
And that building in the trailer doesn't look like Khajiit architecture. It looks Redguard.
