There are basically 3 answers to this question...
1) Who do you think will be in it?
2) Who would you like to be in it?
3) Who would you like that was not in the last one?
I thought I would got for a 4th option and list some I would love to see but I expect will not be in it : (
Big Barda. Leader of the Furies and Apokolips's greatest warrior. The only DC character that is on Wonder Woman's level, though she is even more blood thirsty then Diana. IMO one of the coolest minor characters and even though she has steadily been growing in popularity I think she is one of the most under rated DC characters around.
Since we are still on Apokolips, how about Granny Goodness. One of Darksied's top cronies, slave master, brain washer and well.. she is a DARK character. I have a real soft spot for Granny and would love to see her in Injustice2!!
Manchester Black was the leader of a rouge "hero" squad called the Elite. A hugely powerful psychic , even going toe to toe with Martian Manhunter (though I think he was going to loose before it was interrupted) but what made him awesome is that he had the attitude and I'm not talking about having a union jack tatooed on his chest, though I am sure some of the British competitive scene may look at main'ing him for that reason alone! He was just awesome as all hell and in some ways was the voice of the angst ridden comic reader. "If I had those powers I would fuck their shit up right proper" instead of the normal "goog-guy" stuff. He was just awesome in all ways and a blast to read.,
Parasite, one of my fav Superman villains, though villain is not the right word... Just imagine this guy in a fighting game, consuming projectiles and powering up over time.. starting out a small skinny man thing and ending up a great hulking Bane / Grundy type character by the end of round 3... not only a great bad guy but looks awesome and has a unique power set that could give him sweet and interesting in game functions.
I've always had a soft spot for Atomic Skull... I just loved how deranged he was, thinking he was the good guy and superman the villian and all that. I think he looks awesome but his real problem is that he looks a lot like Ghost Rider. Even so I really dig this guy and hope that one day he gets some new stories that do him justice.

You know I could seriously do this ALL day... I haven't even scratched the surface!!! rofl... MUST STOP POSTING!!!
