Well I hope you will be able to find some inspiration for whatever new bosses they add with the DLC. And I do have a funny feeling that they might try to bring back some of the scrapped bosses. I got a huge bet running that they're going to bring that unnamed spider boss back! But a friend of mine suspects that they're mostly going to be kitchen or food base. I mostly hope that they'll be some more Gun and Run levels. But as a person who loves enemy designs can only hope.
