And I'm pretty sure that the movie is not part of the continuity (because of what was established about the Joker in the first arc of the series).
Barbara allready appears in the comics (next issue will be about her and the new Batgirl) and Luke appeared iirc in previous run with Tim as Batman.
That Dick, Jason and Tim were mentioned in a flashback in the last arc, but we don't now what happend with them.
I doubt that Tim will pop up due to his role in futures end, I Dick has probably good chances to appear at somepoint (he is quite popular at the moment and DC is pushing him a lot) Jason is less likely.
