This thread is useful, I've just paid for the upgrade to PPro2012 (from P7), downloading it as I type.

I wasn't sure I'd ever upgrade Poser, I've used it less and less as modo's toolset has grown (modo601 now has animation, bones and weightmapping, dynamics, fancy hair and skin shaders etc), but I've been wanting to get back into content creation for poser, so having the current version is good. And $125 was a good deal.
