I think just about all we can take from this at the moment is that BT will be involved, in some way, with the Justice League property moving forward. Will he be involved in the live action movie? Well, maybe, maybe not, but it seems likely he'd be involved in whatever animated property spins out of that.
Which I think we all just assumed.
I don't think we'll see a return to JLU or Timmverse days, as much as I'd like there to be a return. DC seems intent on the DCnu, so I suspect the JL movie will probably be affected by that, and by extension whatever cartoon follows.
But since someone mentioned wish lists...
Granny, Hippolyta, Circe and TNBA Poison Ivy would sure be nice, no?
HAD to do it, LOL, my apologies.
