There are two breeds of vendors, the 'character makers' and the 'cloth makers' and never the two shall meet. If V4-WM shall lift depend upon the first ones. Until there are new, wonderfully beautiful and haunting "Vera" or "Alexis" that uses features only found in Poser9/2012 not much will happen. Sure cloth vendors can include a WM version but up till now I always thought that the outfitter was a tool for the end user! Vendors usually include a lot of poses and materials the runtimes would look pretty cluttered and bloated with one more version of everything.
