Correct, and honestly... not much is posted in the PS3 Dev section (except the Site News posts) as 99% of the Dev work/collaboration is done in a private room on IRC among the resident PS3 Devs.
Long ago the PS3 Devs used that section in more depth so you'll see older threads of theirs there, but since other lamers started stealing their work without credits they opted to keep most of the more recent stuff private until it's posted on the main page.
