No upcoming DLC / Add-on / Expansion has been announced so far but there is a decent chance that D:OS 2's loose story ties will come to a conclusion with additional content.
- Malady's request about her pact was never revealed despite being hinted at all game long.
- The God King is still undefeated.
- One of the ending slides shows a map with new locations north of Arx:
- Names of the Regions:
- Beckonbridge Castle
- Void Tainted Ancestor Tree
- Black Ring Ruins
- The Deathfog
- The Holy Mountain
- Montagan's Rest
Comments by Larian Studios
You've mentioned the patch, however what does Larian have planned in the long run for Divinity: Original Sin 2?
We have a couple of things that are in the works but we'll only announce them when we're ready. There's stuff coming, for sure.
To that end: It's early days yet, but I assume the success of number two means we're in line for a Divinity: Original Sin 3, 4 and 5?
[Laughs] We have a couple of surprises planned. But we're going to work on the patch just now, then we're going to work in silence for a little bit so that we can get our shit together and then… yeah, I'm pretty sure there will be at least one big surprise in there.
