One: The title seems to be: Man Of Steel 2: Batman vs Superman, so the rivalry between two "good" super-heroes is absolutely epic, I mean, when has THAT been done before?
Two: Semi-retired Bruce Wayne (Ben Affleck) is going to be using drones to do his fighting,... now, where have we just seen a drone? Man of Steel, when, towards the end, Superman throws down a drone the military was using to spy on him (probably a direct reference to Obama's use of drones against American citizens without any due process).
Four: Wonder Woman appears to be, at this point, Batman's love interest. Whether or not they are actually an item is not known, it might just be that Batman admires her from afar,... like he takes out the bad guys from afar with his remote drones,...
