It would be nice, but I'd be amazed if it ever happened: I suspect Larian are looking forward to their next project whatever that might be rather than looking back, and they aren't really big enough to have two things on the go at once. Pity, it'd be nice to see, although even speaking as someone who has a strong preference for the modern over the old graphically I found DD to be quite palatable (though the voice acting was less good... I think it took the controversy over BD before they took it seriously!)
