While i would not mind seeing more shapely bodies, i would hate to see stupidly oversexualised ones. BG3 ones were good. What i would like to see is more regular body shapes, like more curves around the belly and such, venus belly or dad bod/gladiator body for others, six pack for others and then stuff in-between. Different races could have quite a bit differences in Divinity universe, though in trailer they showed everything was pretty much human with very small differences which was bit disappointing unless they are half-human. So i could see them creating more detailed customiser.
We really don't need jiggle physics.
But i don't think its a loss if they go with something similar to BG3, it worked well for Dragonborn. What bugs me more is how bad the beards look. Hair and beard are the hardest to do on a body, i think lot of games have pretty good hair now, but pretty bad beards - this was the case on BG3, at least on whatever graphical settings i used.
