For a second, I misread your post and thought it said:
Divinity 3: <anything>'s New Hope
Divinity 3: <anything> Strikes Back
Divinity 3: Return of the <anything>
lol
of course that would have to be divinity 4, 5, 6... so we're not quite there yet
I was sarcastic about cheap titles btw :P But I like your idea.
