That of course is the big problem isn't it?  What would be considered game changer?  A lot of Poser improvements are little things that just make it nicer/easier to use.  Like being able to delete multiple objects from a scene by selecting them in the Hierarchy Editor and right clicking delete.  Or having the menus open collapsed.  About the only new thing is AI.  Now it would be nice to get improvements to some of the other Poser features like the cloth room or animation.  The problem with that is that only a small number of people would use it so it is not a game changer.  Me personally, I would like the cloth room (or Bullet Physics Latest) to be able to make cloth work more like real life so we could get rid of stupid conforming clothes.  Most of the time spent making content is wasted trying to get one figure to fit over another figure.  And then all the time spent trying to get rid of poke through.
