Batman is a man with some cool tech. Superman is basically godlike in his abilities. Heck, he can even turn back time.
Kryptonite notwithstanding, there is no contest. None. Zip. Nada.
A “battle” between these two is dumb.
Batman has tricks up his sleeve, and Superman’s powers (especially in “Man of Steel” as compared to “Superman”) actually do have limits.
We don’t know the plotlines it could be Worlds Finest type team-up with an uneadiness but respect of different styles or ‘the fight’ that has been covered several ways including frank millers dark night returns, a novel and graphic novel called Kingdom Come, and a few more. Personally I’d hope for the team up with a potential lead in to a JLA movie, but DC/Warner Brothers has managed their adaptations and characters terribly outside of the batman dark night movies. So I’m not placing bets for success.
