I do expect DLC to come around for a couple of reasons.The first is that there's really a lot of places they could do it. New classes, subclasses, races, companions, expanded story, side-stories, even the "laziest" option of just including a new subclass for every class would be hugely popular and it would be hard NOT to have ideas. The second and in my opinion greater reason I expect DLC is that whatever my issues with this game, Larian really seems to have had a blast making it, like kingsims just said. So I'm sure after they've taken a well-deserved break to rest after all of this, they'd actually WANT to keep working on it and adding more.
