from what i understand, there's a few different programs that could have been made in, even besides the big 3.  the animation looks professional, but since professionals use lots of different tools, that doesn't narrow it down, imho.  i've seen as good or better animation by Little Dragon (though not so long a piece), so it's possible with Poser.  and the question doesn't affect rigging, because i think most pulling Poser figures into 3ds max and such re-rig the figure out of necessity. 

that said, i don't think that's any Daz figure's faces on any of the figures, nor eF's.  it just looks 3d, not specifically Poser, imho.
