Any chance we would see either Constant or Dr Fate??
I think there’s a possibility, as they show up in a lot of comics together. It never hurts to dream.
There’s a thread in the TV forum where it’s being deduced, whether Constantine’s in the cards. Obviously, a possible spoiler if they’re correct https://www.dcuniverse.com/community/boards/othermedia/well-this-is-kind-of-disap
