After seeing the video I wonder even more why they don't bring out a CR2 version.

All settings in the exporter are pretty much fixed except for the UV mapping - and they could have restricted that to the new figures.

The clothing issue is still open in the air. The discussions with SM will probably deal with the smoothing feature which has to translate to autoscale/automorph in Poser. And that might be a very challenging thing to do. And then you probably will have to convert your entire library of clothing through DS4 to get them to fit again in Poser for the new figure.

So no Genesis/V5 for me in the foreseeable future
