I have no doubt Daz will continue to work on their own render program but for them to not continue supporting Poser would mean cutting their customer base by more than 50%. In just a year or two a majority of Poser users will be on Poser 5, for them not to support it wouldn't make business sense. It also would be disasterous for the entire community if the two programs couldn't share items interchangably. I know I couldn't afford both so I'd stick with what I have the most of.
