I presume that one of those would be based on Man of Steel (or Batman V. Superman), set within the same time line/universe/Earth. I'm not a big fan of DC in general but I enjoyed DC Universe Online and Injustice: Gods Among Us (Injustice's story was pretty good). I'm not sure if I'd like a " Superman Game ", but if there's one I can certainly imagine it being based on Man of Steel.
Time will tell. All I know is I've had enough of Batman games (owner of both Arkham Asylum and City, those two are more than enough for me).
