Larian intends to make DD2 in full 3d, not only the characters.
As for me, I'd make DD3 in 3d and think of Beyond Divinity as DD2.
I am pretty sure that the 3rd game of Larian will not be named Divinity 2. It doesn't make sense.
- Command & Conquer
- Red Alert (set before 1)
- Command & Conquer 2: Tiberian Sun (set after 1)
- Red Alert 2 (set between 2 and 1)
- Generals (set between 4 and 1 (or another universe?))
There's no reason they can't use a different name.
Divine Divinity 2 is the currently intended name for the game after
Beyond Divinity because
Beyond Divinity doesn't continue the story of
Divine Divinity. It's just in the same universe.
Also,
Divine Divinity 2 will have MMORPG support, I believe. (Or is it just multiplayer?)
