A "trusted source" has confirmed to IGN that the leaked PlayStation 4 controller image is indeed real, but is only a prototype. The final design could change. An industry source confirmed the same to gaming blog Kotaku.
The image matches up with previous reports, which suggested the PS4 controller would be similar in shape to the DualShock and include a front-facing touch screen. The rumored controller also does not have Start, Select, or Share buttons on its face, matching up with a past report that these buttons had been shifted or removed.
The controller in question also features some sort of illuminated light on its top as well as audio output functionality, similar to the Wii. The pad is plugged into what looks like a development kit, though this is unclear.
