More of the revelations, and breakdowns below:
Punisher, leader of the Hand, with a new symbol (this just came out in the comic book news the other day)
The moon being blown up and the flag (no clue where this is going to play in), I believe the flag is from the Botanical group in X-Men
Iron Man in the God Suit, which we have seen in the pages of Iron Man
MJ as Spider-Man vs. what appears to be Storm as Black Panther.
Winter Soldier returns to shoot Cap.
