Actually, it has been confirmed that Divinity 3 will finish off the story arc of D:OS / DD / BD / Divinity 2; we just don't have any details on the content or timing. Nothing has been mentioned about another dragon knight based RPG, but IMNSHO it would be unfortunate if Larian did nothing else with that concept, or relegated it just to Dragon Commander sequels.
I didn't know that was confirmed but it's great news; have you got a link to that so I can see what Lar said? As it's the sequel to Divinity 2 I think it would naturally be a 3D 3rd person game. Playable character, well I'm not sure about if it will be the Divine or DK or maybe both. It would seem stupid to have a Divinity 3 and not finish the Dragon Knight's story in that game but yet the Divine's story needs finishing too...
I knew Dragon Commander was initially just a test to see how the dragon combat mechanics could be tested for a possible Divinity 3 but ended up being a full seperate game. This shows that Larian are at least considering having the Dragon Knight in the sequel. However as I mentioned above the story arc is about Damian vs. the Divine so how they are going to fit it all together is anyone's guess. It would be interesting to see what they come up with.
