Yep, I just found Steve's response, sorry for speaking before checking (although it was kind of far back ;) ) Saxon, people who don't need the new features would be fools to buy P5, at least at this time. There is only one significant improvement (as far as I can tell) to the old Poser 4: the new Library system. Everything else seems the same. Many might not consider that one improvement to be worth $129.
