A couple of the upsides to using the newer version of the content included with Poser Pro 2012 is that it will include new weight mapped versions of the old Poser 8 humans along with a new weight mapped dragon. This may not sound like much, but there are two compelling advantages over simply re-linking to your Poser 8 content and skipping the Pro 2012 content.

One is that we completely reorganized the content into logically named groupings and sections (people, animals, vehicles, etc.); we ditched the previous version by version listings meaning it's a lot easier to find and use what's included. Pro 2012 includes everything that's in Poser 8 as well, so the only drawback is download time.

Two is that the new weight mapped figures are getting some much needed support, and that is just starting to gain traction. Anastasia for example is an artisitcally gorgeous add-on weight mapped character based on the included Alyson 2 figure that is furnished in Poser Pro 2012.
