PS4 Camera and Twitch "much, much more fun" than Sony anticipated, says Yoshida

PlayStation 4's Twitch app has proved so popular that the console's camera is in very short supply. Sony had no idea it would be such a winner, SCE Worldwide Studios boss Shuhei Yoshida has said.

The PS4 camera has sold over 900,000 units, with an attach rate of 15%, Sony revealed at GDC this week.

PS4 camera stock has since run very low, with some retailers jacking up prices, but this wasn't intentional; Yoshida told Polygon Sony made a mistake.

"It was a total miscalculation by our marketing guys," he said.

"They came up with the initial demand in that conventional way and it was very, very low."

Sony calculated demand for the camera by looking at sales projections for launch games which support the camera, completely overlooking the Twitch app.

"Using the camera to broadcast yourself is much, much more fun they they thought and they didn't quite get it," Yoshida said.

Sony has ramped up production of the peripheral and more stock should already be available in stores, he added.
