Sony boss on Move vs. Kinect, PS3 and PlayStation sales

Sony on Thursday called out the 15th anniversary of the PlayStation, which will be marked by a series of promotions on the PlayStation Network.

It comes as Sony is about to launch the Move motion control system for the PlayStation 3, setting up a holiday sales battle with Microsoft's upcoming Kinect system for the Xbox 360.

Sony said it sold more than 377 million PlayStation consoles and more than 2 billion software units since the line debuted in 1995. In the U.S., PlayStation sales are more than $63 billion over the last 15 years, or about 40 percent of the overall video game market during that period, the company said in its release.
