There's no reason at all to re-purchase everything, poser stuff works in Studio, that much is evidenced by the huge amount of posts detailing it. There are some problems that Daz will need to address but once that's done it should all work. The only differences that will occur will be with studio specific models that "may" use weight mapped jointing rather than cut zones like Poser. The simple fact here is that it's a far superior system to the current more familiar joints as it doesn't result in shattered body parts. Even so, it may not be necessary to repurchase anything. Converting an item from cutzones to single form is as simple as exporting from poser as a solid and then re-boning for Studio. If IF Daz introduce weight mapping properly to Studio. I'm fascinated where people get the idea that they'll have to purchase all their stuff again. Utter nonsense. It appears currently that the major problems with importing poser models is from three things. Path errors in the file, source errors (lights, geometry, etc), and model deformation caused by a poorly implemented filter (cut zones becoming obvious). All can be fixed.
