While the Poser 9-10 can "use" W-Mapping, only the PRO versions can create a W-Mapped figure.

If you absolutely want to upgrade?

The new ftting room in Poser Pro 2014 is worth every penny of the upgrade.

Poser 10 and PP2014 both have the new morph brush, (also extremely usefull), but only PP2014 has the new fitting room.

Poser 1, 2, 3, 4, 5, 7, P8 and PPro2010, P9 and PP2012, P10 and PP2014 Game Dev
