Yeah, the body still has several tri's too. I know at some point the guy goes back and starts deleting alot of unnecessary detail. I think the goal for this character is to be under 4500 polys. There will be 5 levels of detail (LOD).

Level 1 will be 4100 polys for cut scenes and close ups.
Level 2 will be 3000 polys for the main game play.
Level 3 will be 1000 polys for when she is a little farther away on the sceen.
Level 4 will be 500 polys
Level 5 will be 200 polys.

As far as tris are concerned, this guy doesn't seem too concerned about tris, depending on where they are on the model. It's all about the model looking like the concept sketch with minimal polygon count AND deforming correctly when animated.
