Website Scrawl apparently found screenshots buried deep within a publicly available section of Sony's European website showing off some sort of native Facebook integration, as evidenced by a Facebook settings subsection located in the User Accounts section of the PS3's cross-media bar (XMB) main navigation interface.
Unfortunately it's not terribly much to go on, and when pressed, Sony refused to comment on the leaked shots and Facebook integration rumour. However the screens do come from a legitimate Sony source, and it seems highly likely that they'd want to get in on some of the social media action considering they're working diligently to portray the PlayStation 3 console as an all-in-one entertainment hub for the home.
Are you a PS3 owner eager for more social media integration in your console?
