he!  i guess that's one way to look at it.  to me it's more like this: there aren't any "must have" items yet.  those products aren't just breasts, they're custom morphs.  add-ons that really add-on to v3, not items that are good for one render or maybe two before they make your work really repetitive.  i use nbs in every single v3 render i do, just as i do rayne.  there's nothing for v4 that's so basically useful yet.

as for the in time aspect... well that depends on a lot of things.  i don't think wyrmmaster is active anymore, and that leaves a single artist that does that type of work.  i have no clue what posermatic's plan's are.  probably there will be something for v4, but it still remains to be seen.
