I agree with Boni. What I want is a lot of morphs in the face, whether built-in or as an add-on. I like to be able to make Poser figures look like real people - celebrities, family members, politicians, etc. I also want some ethnic diversity. I've bought my share of gorgeous young white characters, but I also want the ability to render different races, ages, etc. (I liked the G2 figures for that reason, though they had other issues.)

But what I think what Poser really needs is figures that will be supported. That is, IMO, what DAZ does right. When they release a figure, it comes with tons of support - textures, hair, clothing, etc. There's never any doubt that their figures will be supported, and will keep being supported. Not sure if Rosity can emulate that, but they should try.
