In the other hand it also might be better to skip that Single skin (Unimesh) upgrade as I doubt that there are enough  3D mesh creators what are willing to make such a jump. A later upgrade on Poser 13 for this feature also might be very difficult as it would simply change the whole tech, so it might eventually be a poser 14 or 15 plan who knows. So I do not really think that this single skin setup room feature will be a simple update of Poser 13 later on.
