Personally, I wish they just plug in a 3rd party render engine, V Ray, Maxwell, final render, Brazil, mental ray, or whatever. The results are so much better, and so much faster. 

The Global Illumination solutions that are apparently new in Poser 8 have been around for at least four or five years in the leading render engines, for example.

In my experience, when you see a really stunning render with Poser content, 9 times out of 10 the improvement comes from exporting the model and rendering in something more capable-- that's what I do, anyway. The world is knee-deep in first class third party engines, you can render from Sketchup in Vray, for instance.
