One of my personal hopes for this gen was a massive improvement in material simulation. So far I've been sorely dissapointed with that aspect, but at least some devs use the improved tech to advance in that area.
Granted, in this case it's used in a pervy way, but the applications for this tech could be potentially game changing.
Show someone hold a characters face in their hands and have the skin and fat deform the face in a natural way, or have characters tread on moss in a forest, just for it to deform and move back up.
Punches to various body zones would deform the body fat and skin realistically.
