Me and my brother looked at it, and decide that the guy isn't John, but maybe another male spartan.
They are both in black jumpsuits, so go figure............

(I'm going through the book Fall of Reach to find out about character discriptions and such. )
I think it was pre-rendered too. But being pre-rendered or not, that's pretty sweet!!
EDIT: Alot of people are saying there is a scope on the pistol, but I have gone through the film twice frame by frame and have found no such evidence suggesting a scope. I also took a good look at both of the children, and it doesn't look like anything the book desctibes he looks like. I can't put a name to the girl, but Maybe someone else can do that.
