DS won't replace Poser, not for awhile anyways. It's not hard to create an app that matches/comes close to P4. P4 is there already to copy and all you need to do is improve the code. P6 had to start from P1. DS from P4. I have DS and the 2 free plugs, extra tools that may help in what I do. But it can't and won't replace my P6 for a very long time. It never hurts to have all the tools you can get your hands on. If Daz makes V4, DS only, that would be a very big revenue loss, I can't see enough DS users making up the difference.
