It's not really a "new Poser store" at DAZ. If you click on the Poser link, it simply performs a search that filters out non-Poser things like Genesis. It's the same Poser-compatible stuff that was always there. Some new Poser things are still coming out, but more slowly. About half of the new goods are for Genesis.

This, too, is not new. When a new product would come out -- Stephanie 4, Aiko 4, Hiro, Kids, whatever --  everything was about that product for awhile. I'm not into the carnival stuff, so it irked me to see almost nothing but carnival stuff for a couple weeks. The same when their Native American collection came out: all Indians, all the time. When they get their teeth into something, they and the vendors don't let go!

Genesis is a more signficant sea change, and it does signal a reduction in new Poser-compatible goods as their vendors focus on Genesis. I think it is permanent, but I don't think it is absolute. The market for V4, M4 is huge, and so is the Poser market. Their vendors won't let them change their business model to Genesis-only. The artists can't afford to live off selling only to Daz Studio users.
