Yes, it'll have even less content but more RNG around already existing content and terrible game-breaking balance issues with every boss scaling their HP to your damage so you never feel powerful.
We'll have to wait then for Legend of Krystal: Antibirth with the real expansion of content and ideas, fixing most of the bugs of the original releases whilst adding actually unique gameplay options.
Edit: I feel like this would've been funny if I stopped a few sentences short but I hate Edmund McMillen so I got a little triggered.
