AS you can notice Superman looks older in his new poster where as official tweets tells us that this movie is been occurring just after two years from General Zod incident. As a comic readers and People who understand DC universe science Superman take lot more years than a normal human being to get old but on the other hand Batman as all of us know that he is wearing the most violent suit in his career in which Batman breaks his own rules to get things done. So what I purpose that what actually going to happen on the basis of the evidence and logical reason.
By combining the authentic news, official cast, comics knowledge and leaks form set this story will run in three Phases where as phase one will start in 2nd scene where Aquaman will rise from the sea and will start attacking the shore where government will plead to Superman to stop it, where SUPERMAN will go to shore to negotiate but after some fight. Nevertheless Jason Momoa is playing Aquaman.
However, simultaneously they will go back and forward from phase 2 to 1, where Phase 2 is all about Bruce Wayne was in the Metropolis City or is going to visit the city around General ZOD event in which some of the Movie Clips of MAN STEEL shows a glimpse of WAYNE ENTERPRISE,
Leaked news indicates that Wonder Woman & Batman cross each other where Bruce is broken and its mention that he is now in rage due the death of a robin Jason toad (which will only be referred and who is actually was the 3rd violent robin died and return as a anti hero becoming Red hood)
Batman is investigating Zsasz who have kidnapped a girl named Carrie Kelley... YEAH!!!! you got it. But its been shared that she did not become robin yet. At same time he is also investigating Superman where the conflict actually starts.
On the other hand Wonder Woman is searching for an object which somehow has to do something with the 4th world
YEAH...!!! the GUY DARKSIED the ruler of Appkolipse which is also known as 4th world but his reference will be shown in the end. However, some villain most probably Metallo gonna kill CLARK KENT or hit him as a citizen casualty not Superman.
However form the most authentic resource claims are that it could be the grave of the president himself Metallo somehow will able kill him and it comes to know that this was the real purpose.
In any case grave is present on the set.
Interesting part is the End credit scene which stalkers had caught on the set after which that Movies Responsible are been seen tweeting regarding Batman while investigating or trying to retrieve Kryptonian information and kryptonite while in the process he will come to know about more dark & cruel research and experiments are going on and that will be Doomsday referring. Another Cut scene of Hal Jordan will be seen talking to John Steward Regarding attack on Hawk eye Planet and asking about Super Man where John Steward dailogue will be that "he is no more" which actually confuses is he died or left being superman
