From the picture, it looks like Supes is wearing his Black suit. So, he might have gone rogue. I mean, honestly, I would love a proper Supes game, but.... This could be one way to have him in a game without him being the controlled and OP character that he usually winds up being. That tends to be one of the reasons he is OP.
I think, if I were going to give a shot to creating a Supes game, I might create a story where he starts off without his powers. Slowly, give him some... and not at full strength when he gets them. Include a way to give him more and more until a climax at the end against a Doomsday like enemy.
That said, I do tend to like Rocksteady games. Let's see what happens.
