This is what I'm thinking is going on after seeing all the images.
These current images ( probably ) take place after superman is arrested by the guy in the black suit and the military. Lex is behind it all.
I don't know if the man in black is a creation of Lex, bizarro? Or an alternative Superman ( ultraman?) Etc..or someone from another planet.
Anywho, the Man in black dons a supersuit like superman's, and does some nasty stuff, all while pretending to be superman.
Superman gets arrested, voluntary gives up, but the man in black roughs him up.
superman is now out of the way, in a supermax prison, and probably kept weak by redsun light or kryptonite, all thanks to Lex.
The man in black decides to bring world peace his own way. He revolts against Lex, and resorts to killing any and all that stand in the way of his goal. He roughs lex up.
The other heroes most likely try to stop him but stand no chance. Several cities are damaged or destroyed.
So they free superman after learning the man in black framed him.
Lex probably even helps, an Enemy of my enemy is my friend type of situation.
What we're seeing is a super fight between superman and the man in black. Images in the baseball stadium of someone being drug along the ground is part of it.
Metropolis ( mostly ) evacuates. We seen images of people on the bridge with suitcase, shopping carts full of belongings, etc. All fleeing.
The hole superman is in is a crater his body mostly likely made after being super punched down to the ground.
Again, I'm just guessing. I may be way off.
We shall see.
