I think the idea of having a single mesh that can morph into a variety of characters one with excellent possibilities, especially in the area of science fiction imagery. After all, we do something similar ourselves - male and femal aren't different conceptually IIRC. I must admit I'm not 100% sure about a neuter base rather than a flat-chested female base, but I think I get the logic behind it. A little bit PC but it's probably easier to "become female" and "become male" with equal quality if the base is somewhere between those states. So perhaps it avoids "favouring" one sex over the other, I'm not 100% sure.

I see all SORTS of potential problems with the route, and must admit that I'm surprised at the rapidity of this current step - from V4 to Genesis. V2-V3-V4 was very slowly going in this direction then BAM! Lots of changes all at once.

I'll enjoy looking back in a few years and seeing how well the idea worked.
