Brilliant! I love ZBrush, and loved Sculptris before I had ZBrush, but for me the slowest part of modelling is building a decent base-mesh on which to sculpt (I'm not very good with Z-Spheres), so I'm most excited about the GoZ feature.

Make any shape you can imagine in Sculptris with dynamic tessellation -> GoZ to ZBrush -> Retopo + ProjectAll -> Crazy fancy-pants multi-res and HD sculpting and painting in ZBrush
