Outside of the proposed Justice League movie itself, I definitely don't want to see any more Batman for a while.
I think Batman works best in a Justice League story when his role as a detective and driver of fancy cars and planes is emphasized over his punching people in the face. The problem is that very few Batman writers seem to understand that 'detective' does not mean 'has a fancy computer machine that tells him the answers to everything', so we rarely see Batman do anything that makes him appear particularly good at detecting and figuring things out.
