As a programmer i also would sometimes like to kill someone at microsoft, when i'm forced to make an old software compatible to the newest version. Until their own DAZ-studio is not a real match for Poser, they get their money from Poser-users, if they like it or not. So they are forced to make their products compatible, if they don't want to be kicked out of business. So i think, the only question is, how long they need to do so and if they give away those updates for free. I'm quite confident that they do so, because DAZ always was fair in their business in the past.
