For those who have only Poser 5 this definitely a good thing but for those of us with only Poser 4 its hard to get excited. If the patch allowed you import Cloth and Hair room simulation then it would be worth upgrading to Poser 5. For now it just allows Poser 5 users to do what anyone could do with Poser 4 (or anyone with Poser 5 plus Poser 4).
