As far as price point goes, is there really all that much difference between what CL charged for Poser ProPack?  IIRC, the price of the ProPack addon was somewhere in the $200 to $300 range.  For that you got the setup room, some plugins, and python scripting.  There might have been more that those seem to be the major ones. 

Now we have Poser Pro.  A $200 upgrade that can be likened to the old ProPack.  Only with this release you get a 64bit app, network rendering, HDRI, gamma correction and some plugins. 

If you compare the full cost of Poser Pro with the cost of buying Poser4 and ProPack, I don't think the price is all that different.
