I shall wait until Poser 8 has been out for a while before I do anything - see what the first users think -, and then I shall be quite happy to upgrade providing Poser 8 is an improvement on Poser 7 (which I find has  sluggish response to parameter dials compared with Poser 6). 
I may not like the interface changes, but will get used to them.
I don't buy thousands of dollars worth of bits and bobs, though I buy quite a few; and I'm quite happy playing with dollies and dressing them up (or down ... ) - for which I blame my sister, who used to insist on me helping her with her cardboard cut-out dolls and paper dresses.

They key feature is, of course, that it will run on my G5 and not require a Mac with an Intel chip.

And I would like the Content Paradise forum working again and a few flying pigs.
