After reading many of the Poser forums, I expect that I may be one of the few people in the Poser community excited about PPro.

To me, network rendering is crucial. I run a 7-machine home renderfarm for animated projects and I would not be anywhere near as productive without it. When you're dealing with 20+minute render times per frame, being able to get animation done quickly by throwing more processors at the project pays off big.

Collada in/out is invaluable for transitioning content from PPro to LW or other apps. LW hosting is apparently still in the works for PPro, and that would be very useful for me in my planned projects.  If it does nothing else, it will still be worth the price tag for the full version.
