This mean Superman will do what Superman did to batman in the first encounter in 52 comics. In time when Batman learns more about Sup and his weakness is when he'll be able to beat him. We will see if he keeps his words and his realistic approach.
That's pretty much what I said. They are not adapting the story but it will "help to tell the story". So it is an inspiration to the movie...
