So Zack Snyder confirmed that the Man of Steel sequel will have Batman.
I never read comic books growing up, so I don't really know how this will work. In fact, I can't picture it working. Superman is capable of throwing locomotives through buildings and is so powerful that when he takes off too quickly to fly across the earth, he leaves a crater behind him. Not to mention he has lasers that shoot from his eyes.
There's no need for Batman. In a world with god-like superheroes, Batman becomes retired.
