Since Daz studio pro free.

now has a better secondary  render engine

Better nonlinear character animation system

more versatileand better looking default figures.

it can access my OLD poser 6  mac formatted runtime without Adobe Air/Flash

it has an officially supported direct bridge to Iclone

the same game content export options to unity,unreal etc as the 

paid poser "game dev"version etc etc.

Yet people still shell out money for poser because they just prefer it over that free program

the same will remain true for users of Windows and OSX.

Now and in the future.

Actually once Iray gets out of beta, it will be the default renderer and 3delight the secondary. If you load the beta, it is set to render any scene in iray first.
