Well, the new Poser 7 sr3 release updates poser 7, so what you see in it is the same as Poser pro now.. BUT the downside is all your old P7 stuff needs to be updated.

They did corrections to a number of render issues, and the option was to still do them "wrong"  and keep things consistant with P7, or update P7 to do things properly and update P7 to the new proper Poser Pro standard, and they chose the later.

Way too many people take way too many things way too seriously.
