Well that is a very difficult statement to prove or disprove.  Yes there is more support for Genesis appearing every day and that will clearly continue.  On the other hand there are new products for V4 being launched everyday and I suspect that will continue for a while yet.  With the number of people on a very tight budget there are bound to be some users that would love to use Genesis but cannot afford buy enough Genesis stuff to meet their needs.  That is not a fault of Genesis just the reality of the situation for any new figure. 

Many users using V4 and the less supported figures do not buy many products but make their own and the majority of users of 3D art software do not frequent the forums.  

Clearly as Genesis gains ground support for V4 and other figures will decrease.  Any additional figures will further fragment the market so I really can't see everyone moving to a single figure.  V4 came the closet but those days are long gone.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
