Found this in the press release

"Uli Klumpp, Director of Product Development at e frontier and long-time Poser Product Manager said, “Compared to all previous versions, this release is the most significant one to date. Poser 7 will have a powerful combination of new content, new features and improvements that modernizes and invigorates its foundation. We have also added many features that our long time customers have requested. The bottom line is that both the Poser professional and the casual enthusiast will have more robust and more powerful 3D figure design and animation software. Poser 7 will make their creative workflow more enjoyable.”

In particular the ".... we have also added many features that our long time customers have requested..."  sounds very promising  :-)
