If the new gaming version of Poser Pro is going to be able to weld together cloths and figures and remove hidden polygons then having a high resolution head would be a good thing.  It may not fit the " normal style of poser renders " but it would be welcolmed in  areas where you would only see heads and hands of people such as when wearing business suits, uniforms, etc.

Ideally it would be based on a sub divided head of a figure such as Rex and Roxie, so that you would be able to attach it to the proper body subdivide the body to match the head and be able to use it as a nude.  Or if there is a way to blend in the head to a body and remove the seam.

Another nice to have feature would be to have a full body rig so that you could conform cloths to the "body" so that you would not have to go to two or more locations to move the body parts of the cloths to pose them.
