Sounds like, for all the moaning and groaning over Superman killing Zod at the end, it seems to lend itself to this film where Batman has to show Superman that killing is the separation between "us and them", since the character takes such a hard line on it.

EDIT: And as much as they are declaring this separate from The Dark Knight, I can see some allusions to that series where Batman is an older-grizzeled version of himself and is called into action to guide Superman, kind of a reversal from The Dark Knight Returns.
