V4 will retire when 3d software stops using polygons as the basis for modelling. 

Otherwise, I think it's pretty safe to say that there will likely be software around that will permit you to load, pose, and render her.

I'm more worried that the continuing trend of populations away from desktop computing towards low powered mobile devices with microscopic screens will eventually leave desktop users priced out of the market.

But the large numbers of baby boomers who don't want to have to wear surgical loupes to use a computer will probably prevent that from happening in my lifetime.
