I'll probably get version 8 as I didn't upgrade to version 7. Any differences between 6 and 8 will be worth the upgrade. Got Poser 3 on a mag years ago and upgraded to each version, but was short of cash when 7 first came out. In my experience Poser is like Star Trek films, the even numbered ones are usually better! (Until some smart a*se comes along, reboots the franchise, and possibly makes it better ;)  ).
Just pray to the programming gods that we get a better renderer, and for newbies/ lazy/ on a limited schedule the mythical "Make Art" button and Alan Alda figure!
