Casuir's guy is intended as an 'elite' or veteran version of the basic chaos warrior. These are the chosen warriors, and are the first chaos units that are really faction specific. There will be Knights and champions above this, who will get progressively more extreme.

As Casuir has pointed out, the 'neck' bone determines where the head is and where it pivots. To move this would require a complete new set of animations and all the resources that go with it. Not going to be practical for the results. All the artwork in the armybooks shows heads sitting on shoulders.... and I think that is how it should look. If we end up with heads jutting out the front, then they will be fixed and part of the torso, not animating.

I'm stuck between making more Dwarves or filling out the ranks of Chaos ...ahh...what a dilemma!
