I think knyghtmare2021 may be referring to some of the terminology used in the statement such as

"Smith Micro, the parent company of Poser, announced Renderosity.com will become the official marketplace for Poser content."

Which does make it sound a little like Renderosity will become an official Poser market place, like some sort of licensed dealership or an acquisition. But I don't believe that is the intention of the statement, SMS has had official partners in the past that were in no way exclusive to only selling content or providing forum support for SMS software. SMS tends to like this kind of language in their statements, just look at all the 'Poser Ambassadors' getting about. I really wouldn't expect a great deal of change on the Renderosity side of things, except for maybe some new content in store and possible a few new content creators appearing. In my opinion Renderosity has always been pretty well partnered to SMS/Poser and offers fairly broad support to the Poser community through vendor support, SMS program sales, promotional competitions and dedicated forums. But that doesn't mean there isn't room here for a broader community and a marketplace that supports many different platforms, which is one of the best things about Renderosity imo.
