Now there is more talk of introducing everyone (including the rebooted Batman) in JLA.

Batman-On-Film is a really reliable source (they broke the casting of TDK and TDKR before anybody) so there might be a nugget of truth to this.
I don't mind them introducing Batman in a JLA movie since he's at the front of the public consciousness, but I still dislike the idea of introducing EVERYONE in a JLA movie and doing solo movies later, for reasons I've previously explained.
DC need to stop being so embarrassed to take cues from Marvel. New 52 wouldn't be so widely hated right now if they just started their own separate thing like Marvel did with the Ultimates. And I know I'm not alone in thinking the Avengers method would work best for JLA.
