I sometimes wonder how many people use the current animation capabilities of Poser. I think that Curious Labs is absolutely right to add and improve features like animation, hair systems and collision detection. And I believe that those type improvements will figure into many folks buying logic - but I doubt any large percentage of Poser 5 purchasers are going to use it much. Nor are we going to toss out the gigabytes of Poser files we've accumulated through freestuff, purchases and our own hard work just because there are new models available. I still use P4 clothing with Michael/Victoria figures (usually the head on a P4 body) all the time.
