It only took four days of US and European sales for the PlayStation Vita to break one million. Sony has sold 1.2 milion Vita units, it said in a press release today.
The powerful handheld system first launched on December 17, 2011 in Japan, where it sold over 300,000 units during its first two days on the market. Sony released the device last week in the U.S. and Europe to some excellent reviews.
Sony's main competitor in handheld gaming, Nintendo, has sold 15 million 3DS units worldwide since it released its hands-free 3D portable in early 2011.
