As someone mentioned previously, the folks at DAZ didn't get to see Poser 6 until the day it was released. There is a LOT to learn in this new release, and you can't learn it in one night. In fact, you're talking quite a while to learn about all of the additions and changes and how they relate to each other. As far as updating products to be P6 compatible, there is a lot more stuff created by independent merchants that are in the same state as the DAZ stuff. The main reason that people make things Poser 4 compatible is because it's the lowest common denominator and that way they know it will work for everyone. If it went the other way around and everyone made their products compatible with P5 and P6 only, those who use P4, Pro Pack, or DAZ Studio would be very unhappy about it. So you go with the solution that would benefit most people.
