I think it will take quite some time before the new figures really take off. Compatibility with Poser is definitely one thing. Another is that it will be a while before there's enough content/converted content for it. By that time, things will have found a way to become stable.

The majoriy of users are not going to jump to new figures overnight. I for one can't even work with Daz Studio, since it doesn't allow custom created dynamic clothing, which I use for pretty much all clothing.
