Rigging weight maps for clothes in fallout or oblivion takes seconds with weight copy scripts. I would guess they would add a script to do this in poser/DS to make content creation quicker, then adjust as needed. I would love to see weight mapping because then lower poly models could be used. This would open a range of possiblities for the artist that does crowd scenes. It is rare that I go anywhere in the real world and see only 2 people posing with each other. Though I admit I do not visit old temples.

 

Weight mapping could also allow proper rigging of fantasy armor that does not bend like rubber.
