One of the devs on twitter said that WB has a say in who gets DLC slots. So there's that.

My most cynical self wants this to blow up their faces; at this point, so far away from launch, most of the casual players have moved on. I'm not sure these characters will do as well as they hope.

And at this point I wish they'd just fucking announce some horror-themed clusterfuck fighting game and get it over with. That's what this is building up to.
