It looks like there was some huge "Batman vs Superman "plot spoilers leaked on the net. And from the looks of it there are some big things that will happen post "Batman vs Superman" or "Man of Steel 2" if you want to call it that.
A user named "James Woods" at NeoGaf discussed speaking with someone who had been let go by the art department for the Man Of Steel. In their discussions, this person revealed Batman vs Superman plot spoilers. These are the things he said.
-Superman's massive battle at the end of "Man of Steel" had massive repercussions. Batman has cooperated with someone to form some sort of coalition to make sure it doesn't happen again. Maybe it involves Aquaman. Apparently the "world engine" operated by Zod in "Man of Steel" really messed up the oceans and the fish.
-Batman's got some major issues. A rift between him and Robin exists because of Robin's unspecified betrayal. He's also got a mole in Wayne Enterprises, and that mole is actually Wonder Woman, tracking an item important to the Amazonians.
-Lex Luthor and Metallo are the antagonists in "Batman vs Superman".
-Lex Luthor spends time "in the shadows" so he's not face-to-face with Superman that often. He will play the role of a manipulator in "Batman vs Superman" Maybe he's involved with Batman's coalition?
-Lois Lane investigates Lex Luthor, who has enough money that he purchases the Daily Planet as a "P.R." move.
-Metallo apparently murders the Man of Steel
-Superman clearly lives and will live "in exile" while the government forms a Justice League.
What makes these spoilers "believable" is that recent events point out that some of these things might actually happen.
Batman and Robin having a falling out was one of the earliest plot leaks to happen. Jason Momoa being in contention to play Aquaman. Metallo being included in "Batman vs Superman" was also being talked about before. There's also the fact that according to movieweb.com, Joaquin Phoenix is close to signing the contract saying he will play Lex Luthor.
However all of these are just rumors so take it with a grain of salt.
What is confirmed however is that "Batman Vs. Superman" comes to theaters May 6th, 2016 and stars Amy Adams, Henry Cavill, Ben Affleck, Diane Lane, Laurence Fishburne, Gal Gadot. The film is directed by Zack Snyder.
