I wasn't all that surprised at the move. I've noticed more and more Renderosity merchants starting to sell their products direct through CP.  When I visit CP I use a book mark linked to new products but all too often it seemed to be "older" products from a new vendor. any new Renderosity stuff seemed to arrive late several pages down.

If I were Renderosity I would not be too happy at having my venders poached and lower profile in the display of pages.
