The Playstation 4 camera named “Eye” is looking like a separate purchase. In a recent video featuring the Dualshock 4 controller, it states that “Playstation 4 camera may be required and is sold separately”. I would suspect that the PS4 Camera is a must have anyways and most likely Sony will offer a bundle that includes it. More details should be know at the E3 show in a few days.

Update: The PS4 Eye is going to be sold separately for a price of $59.
