With the announcement of the plans for there cinematic universe, DC and Warner bros. have a pretty full plate but that's all assuming that BvS is as good as we're all expecting. As you should know by now, MoS was the being of there new cinematic universe and even though a lot of people liked it(myself included) the movie still is on the receiving end of a lot of hate, so who's to say the Batman V Superman:dawn of justice won't be the same.
Being that this movie has been fantasized about and the very argument of who would win in a fight, Batman or Superman, everyone is gonna wanna see the conflict that leads to the big blue boy scout and the dark knight fighting and I have no doubt that we won't but the films director, Zack Snyder, has already told us that the movie isn't just a fight and that the two heroes will work together at some point in the movie which is probably for the better. As far as set up for the justice league movie, Ezra Miller, who has been cast as the flash, has been talked about in recent rumors stating that he may be apart of BvS but at the most I'll more than likely just be a cameo like Stan "the man" Lee. Princess Diana of the amazons will also play a role in this move, being played by Fast and Furious actor, Gal Gadot, Wonder Woman has been seen in the trailers engaging in battle so we hope to so some great action scenes with her.
