The question on whether DC will decide will follow the Marvel way and include mid or post-credit scenes that expand the universe has been a mystery since Man of Steel. We didn’t get one in that movie, but Batman v Superman is paving the way for the DCEU so it would seem right that they start giving us those scenes that make us remain seated when the credits roll. Turns out they might not be going the way of the Marvel, but something else pretty cool.
According to Heroic Hollywood, there will be an montage sequence similar to the Watchmen opening sequence showing the Minutemen, that shows the Justice League members kicking some ass that leads into the Justice League movie. It’s a beautifully done sequence in Watchmen and if you haven’t seen it check below. This is all rumors of course.
