Actually eFrontier invested the money to bridge the gap between Poser and higher end apps.

Shortly after Poser 7 was released, they purchased the Poser Fusion plugins and added them to the first Pro version of Poser. 

IIRC, there is a thread in one of the offical Poser forums over at RDNA detailing SMS's reasons why they made the choices they made.  One of the biggest was that they did not want to tie their app to another companies development schedule.  Another had to do with Triax being trademarked or whatever and SMS choosing to continue as previous owners have with an open file system.  There were others but these were two of the biggest.

Wasn't Genesis supposed to be the greatest thing since sliced bread to hit the Poser/DS market?  Wasn't it supposed to be the be all end all of all figures? 

That lasted what?  Two years?  Now it's back to the gender split. Two steps forward and then three steps back.
