V4 WM, was out last month, at least the extra bits needed for P9, and PP2012, to add onto V4.
The additional bits (inc clothes) are available from Poser Place, here:

Daz, still currently has V4.2 (as a freebie, for your V4WM's base figure).
There are other figures in the works for the WM treatment too.
(I'm still kicking around with my P6, it could be a whole decade before I get around to trying her)
