Have you heard? Andrew is introducing the use of PBR within 3D coat. Here is some more information I found on The Foundry websites about other things coming someday -
He supposedly hired 3 additional programmers (not counting the guy who handles the MAC and Linux builds, and Raul, who handles the LiveClay tools) earlier in the year, and one of those is supposed to be working on expanding the Retopo room to be a more full-fledged Poly modeler, and they plan to implement NURBS mainly for export to Manufactuing standard file formats (ie., STEP, IGES, etc).
After PBR, I think Andrew plans to add true Sculpting layers (per object) in the "Sculpt" workspace. You can already do that with the image based sculpting toolset in the Paint Workspace, but most people are going to do most or all of their sculpting in the Sculpt room/workspace. Then he will likely handle the poly modeling tools. So, I think that is the progression.
