I'll have to find the quote, but I'm certain I read (or perhaps it was in one of the videos) where Swen stated that DD was originally planned as a turn-based game, but their publisher insisted on real time.
That is correct. None of their titles were conceptualized to be action games. That was due to the publishers demands. I don't know why Demonic is claiming the Action RPG thing. Swen stated exactly the opposite many times when it concerned the divinity games and what they always dreamed of making.
