3DV stated that the webcam would be priced comparably to other peripherals in the gaming market such as the PlayStation Eye: less than US$100,[17] with a bundled US$69.99 price mentioned as a possibility.[14] The webcam was to include software development kits for camera control and gesture recognition.[16] 3DV originally projected the ZCam to be released before the end of 2008,[14] then later revised the projection to 2009.[21] In March 2009, the company agreed to sell its assets including the ZCam to a third party,[7] later confirmed to beMicrosoft.[8][22] Following these reports, it was speculated that Microsoft would use the ZCam technology for a motion-sensing controller system for the Xbox 360 video game console or its successor. This speculation increased in the month leading up to Microsoft's announcement of the Project Natal 3D depth-sensing device at the 2009 Electronic Entertainment Expo, during which leaked information about that device prompted frequent comparisons with the ZCam.[23]
