going backwards...

it's going to take something to get people to use anything but one figure anyway. merchants are all switching to v4 only, and everyone who critiques v4 is told that in a few months, it'll be all v4 and nothing else in the galleries.  and that's probably accurate, even though v3 is so different in appearance ,  i think of v4 as just a whole different figure.  that is, i think they don't fill at all the same purpose in terms of figure types, and i can see using both.  v4 may have better bending, but miki still has better expressions, body shape and general facial realism than either, imho, but i haven't replaced all my unimesh stuff with her and i've bothered to acquire v4.

i think new figures appeal to the people who bother to learn new things and use new technologies and use more than one figure in the first place.   some people had to learn to use apollo, but those that did touted his advantages loudly.   and the most praise was about his most difficult and least standard aspect- his rigging.

personally, i'm interested in new figures because of the diversity they'll bring to my renders and the advantages that come from many innovators instead of one or two groups.  i'd rather have much, much better bending and a realistic and different body shape.  if a figure isn't much different in the body than an existing and popular figure, i'd much prefer body morphs and a new head.

bones for breasts - it seems like a good idea to me.  i've always heard good things about figures that did that, and i've often wanted them for other figures. 

i don't think there's a need for another surface on the eye. v4's eye has all these surfaces, and i can't see a need for them at all yet.  if i want to layer types of highlights, i can do it in the material room.  i'm not sure what benefits all the different layers are supposed to have. that isn't to say there aren't great uses possible for all those layers, but i've yet to see results on par with eye props that had fewer layers.
