I must read the SM site differant than you.  Poser 8 to PP 2010 is a sidegrade not an upgrade and thats not free.  Buying Poser Pro now and updating it to PP 2010 is free.  I have the option to upgrade my P7 to P8($99) or sidegrade to PP($200).  If i upgrade to PP then I can take that to 2010 for free.
