As someone who does use the Cloth Room, I don't think there is that much "betterness" in updating. Maybe a bit faster in some calculations because of better coding.

Poser7,8 and 9 do have many other and better options than 6 in other things. But the clothroom remains about the same.

There has been some chat in the MAX Forum about Dynamic stuff and Poser.

Might want to check it out?
