Dan Farr gave us some info earlier. To quote Dan: "Victoria 3 will have two base version. One that will have the new joint parameters and texture UV's and another that is backwards compatible with the previous Victoria clothing and maps. Because of the new mesh structure (higher polygon count) previous morph target packs will not be compatible." She'll work fine in P4.
