Looks like the end. Gow3

From what I can tell, those statues are either like the statues over near that volcano in Greece/rome whatever, The people were literally flash petrified by the lava, OR it represents memories. Meaning the trailer is just an expression of their feelings.

Dom is more of a main story character then Marcus I think, the statue he see's of the woman might be his wife that he's searched for, given the expression on his face, and it getting destroyed might mean she is dead. They are all tired, by the way they look, and the fact that he just gave up and was ready to get shot. As for that being Anya, It might be, Might not, Wouldn't your army get desperate if you got down to only a few hundred people?

I heard rumors of there being a "friendly" locust who would join their team in the third, one who didn't have a Hive mind personality.

As for the third enemy, well my guess is the game will either end with a big bang, or they all die. Thats not earth, Why don't they just LEAVE.
