Yeah, seen it. 5 min, 1 min, not that much of a difference since he isn't shooting anything.
Killzone 2 has a similar scene which looks around the same or even better with sev starting with looking in the mirror and then moving in the ISA headquarters.
Lets see gameplay and then I will agree it looks great and is comparable to Killzone 3. The credits is what was used for trailers as well.
