Sony has confirmed that Ratchet & Clank: All 4 One will feature stereoscopic 3D.
Joystiq noted the inclusion during a SXSW Interactive demo event.
All 4 One is a four player co-op title which stands outside the core Ratchet & Clank story so far. Qwark and Doctor Nefarious are the other characters, and drop-in drop-out multiplayer is the go.
It's due exclusively for PlayStation 3 in northern autumn.
