Yes I also heard of La Femme (LF1), and also doubtful whether it will take off as a successor to Poser's go-to figure, so I am observing at this moment on.
Aside from Dawn, there is also Project Evolution (PE), but so far very very few contents are created for that figure. I did not like the basic body shape of PE at all, looks a bit too chubby.
La Femme needs to be as good as the current Daz G3F or even G8F figure series in order to gain more attention and support from the Poser community, otherwise it will just flopped like all other previous failed products.
