I think the "true"
Divinity 3 will be
Original Sin 3, since it attracted the most players and it has the mechanics to support the kind of story Swen wants to tell (meaning: a biiiiiig and epiiiiiic one). I wouldn't give up on another Dragon Knight - Game, though. The idea behind playing a shapeshifting dragon is too unique to slide and Larian likes to come back and make older stuff better
