Sony says it underestimated demand for the PlayStation Camera, and the PS4 peripheral currently has an attach rate of around 15 percent worldwide. That's according to SCEA's Chris Norden; SlashGear reports the senior staff developer revealed the figure during his GDC presentation yesterday. Sony recently announced it sold more than 6 million PS4 units, so doing the math that equates to around 900,000 PS Cameras sold at least.
GameSpot adds that Norden asked consumers to "please be patient" as Sony seeks to increase stock, but he didn't put a timeline to the peripheral's future availability. The PS4 Camera retails for $60 in North America, and it isn't included as standard with the console, unlike Kinect for the Xbox One.
