BTW do you want to see the Batfamily in the movie? If so, how many members? Nightwing? Any robins? Tim Drake? Damian? Redhood?
That's a tricky one really, because it all comes down to the kind of story Reeves wants to tell, and the kind of Batman he wants to present.
Also, the film doesn't want to get too bogged down with back story, so introducing a large bat family might become too onerous, story-wise.
I think Dick will be referenced, or even make an appearance in the movie, especially as we're getting a Nightwing film. Same goes for Babs, obviously. After all, the audience is very familiar with both already, so it won't take too much exposition to have them in it.
There can be passing reference to Jason's death again, but I'd baulk a bit at trying to crowbar in Red Hood, Damian or Tim, as I could see the thing just getting bogged down in explaining who the hell they all are. The Batman needs a clean, concise, stand-alone story I think, that'll be accessible to the whole audience.
If Red Hood were to be used, it'd have to be in a future movie after this one. I don't think Tim or Damian will get a look in though. Tim is really too similar to Dick in many ways, and to have Damian means getting into Bruce's history with Talia and Ra's, and that'd just get too unwieldy.
So, I see Dick and Babs referenced, but we're probably looking at Batman being largely on his own with Alfred again in Wayne Manor. The nature of movie making rather precludes an extended family with years upon years of history to work through.
That's why one day I'd still like to see a TV version of Batman done, where this stuff can be better explored over a longer timescale. Make it an Elseworlds story, where each season is a different Batman, starting with Bruce decades ago, and following the family as they grow and change.
