The reason I would think of those features as expensive, is that they are pretty much on the forefront of the technology at the moment. Hair dynamics in particular seems to be a hot topic for computer graphics research. I've gotten hold of a few tech papers detailing cloth physics and hair modeling, and it is not a trivial problem. Just consider how much money was spent on Aki Ross' hair in Final Fantasy as an example. I may be out of line, but features that you would tend to relate to very expensive programs like Maya, sound like they would be expensive in a program like Poser as well. The combination of Poser 4 and the Pro Pack is a little over $400--Somehow I don't see it getting cheaper with added features. Maybe I'm wrong--hopefully I am, but I'll believe it when I see it. If it turns out that my speculation is wrong then I'll be eating crow, but . . . I've been playing around with programing my own cloth simulation application--just to see if I can really. Anyway, even if they do release all these features within the same Poser 4 price range, they would be computationally expensive. Next to price, I'd be interested in system requirements. If I have to upgrade my poor old computer (A Pentium III 400 MHz), which seems pretty likely, then that's one more expense that unfortunately is a limiting factor for me.
