I was debating upon whether or not to reply.  In my opinion, V4 is designed to be a counterpart to Apollo.  Some of her features, particularly her mapping, scaling, materials, and rigging, are directly related to those of Apollo.  It is my opinion that these features were incorporated in such a way as to deter the release of Anton's Venus figure by making her obsolete.  This is not to say that V4 is not a good figure or that DAZ didn't put a lot of work into her.  I do think that they sought out what the most current innovations were in poser figures and implemented them into their own product.  I definitely prefer her over V3...
