Quote - Personally, I found V3's mesh terrible and completely useless for morphing. ...

Probably true, except around the lips, according to Esther.

Personally, I have found V4 reasonably suitable for my needs, but then, I don't stray far from the sandbox. And gleefully purchase improvements to the figure like the shoulder-fix, only just because I've been able to get her to work well for me.

Whether V5 (if such a creature is in development) will be very attractive to me will depend a lot on how much of V4's stuff she's able to use without much mucking around with the mesh to get stuff to fit. Clothing quality has improved some since V4's been out, so a lot of my V3 stuff is in mothballs, but you wait until I get those folds and wrinkles sculpting working properly in the new Blender... V4's getting a really flash new wardrobe from her older sister.
