First Look: Saw 4

Lionsgate has released the first official photo from SAW 4, which can be seen after the jump.

I'm not quite sure what is going on in this trap, but there does appear to be a timer on the wall counting down to something. I would guess that the numbers are minutes, which means there is about an hour and a half left. And what is with the pig mask? It appears to be a woman in the chair. The photos on the wall show a guy and a girl, while the writing above says "See What I See". Could the guy in the photos be the new jigsaw?
