Okay, this one from Lionhead looks very interesting.
Edit: it also sounds like what ILM developed for Davy Jones in Pirates 2, in order to overcome the poly limits of the previous versions on Zbrush (they managed about 1.5-2 million quads at that time)
Edit2: super amazing, forwarding it to our own tool programmers, probably gonna add some questions tomorrow
So their tech is that good huh?
