Wonder Woman arrives on June 2, 2017, followed by Justice League on NovemThe Flash on MaAquaman on JShazam on ApCyborg on Apand Green Lantern Corps on July 24, 2020. Just a guestimate, but one that would be pretty cool to see onscreen. The suit is changed, the Batmobile (or whatever vehicle) gets loaded up with weapons, the switch is flipped (cue those sparks), and Batman zooms out of Wayne Tech towards the battle. If you thought Batman was brutal with his Bat mobile carnage in Batman v Superman, it looks like Justice League will be upping that ante. We can see that the vehicle will pack plenty of firepower, as there is a barrage of missles tucked under the passengers side of the car, just before the rear wheel.
There's a Bat-vehicle in the shot (the new Batmobile?).
