The Millenium family is pretty well established and has a lot of stuff out there, both free and commercial products. It would be very surprising if the market suddenly decides not to develop new add-ons for products with such a huge penetration in the Poser community. The appearance of Victoria and Michael did not make Posette and the Dork obsolete, nor will the P5 figures make any of the older figures immediately obsolete. And it will take some time before the P5 family is as well dressed, textured and equipped as the Millenium family. Furthermore, there will still be people that stays with Poser 4 for the time being and hence have no access to the P5 figures. Mike and Vicky will not lose their jobs with the introduction of Poser 5, but they might get a little less attention.
