They're not really talking much about how DLC works, but if I had to guess I'd say it works more like Dragon Age where it's set pre-ending. They have basically said as much. I do hope we get something like Overlord though. I am pretty certain it's not in the main game though. You don't hide features. Story, yes, features, no.
