CL has a new owner now, and they seem serious about advancing Poser. I don't know if they'll really get Poser 6 out by the of the year, but I think they will get it out. And I'm also pretty sure DAZ won't support it. If they're not supporting Poser 5, why would they support Poser 6?

And DAZ content is not necessarily Poser content. D|S files cannot be read by Poser.
