Yes, it seems some vendors are migrating to DAZ. Fabiana and Lilflame have moved a big chunk of their catalog to DAZ, so I guess Lully is next and who knows how many more. I was more concern of not able to access my purchased items, but they're still showing up in my inventory.

I hope they don't abandon Renderosity entirely. I now rarely buy from DAZ due to their unnecessarily confusing and almost always broken mind bending sales tactics. And also their poor filtering system. Renderosity is much simpler and better experience in my opinion. 

Cheers
