I don't think the men have exactly thrived under CoP with quads. I don't see that at all. Most of the men struggle with making their quads consistent, and trying to figure out the best strategic use of a quad. Some of the men (like Chan) who do perfect a quad, often do it to the detriment of their triples. And I don't see any men who have yet managed to perform quads on a regular basis and escape injury -- that is the other reason, IMO, why a lot of men are cautious about attempting them.
The fact there may be "nothing really new with the women" likely has more to do with cycles in skating, and IMO, also a lot to do with the elimination of figures resulting in many ladies having problems with mastering their edge technique. CoP has merely complicated issues that already existed among the ladies field.
I'm also not sure it's necessarily true that there are more falls because "skaters are trying more jumps."
