What I'd like to see is very simple:

A well-made figure that works equally well in Poser and DS, without the need for an import script.  No favoring one format above the other.

As for content, there are plenty of vendors -- more than enough to make Dawn products for both Poser and DS.  I don't think content-creation is a huge issue.  If a figure is popular enough, the content creators will come. :-)

And while I definitely don't want to see V4 put on a shelf (way too many people have way too much invested in her), I do think everyone is ready for a cool new figure, with lots of potential.

I love me some Modo!  :-)
