PlayStation 4 has sold 4.2 million units

Newsbrief: PlayStation 4 continues strong sell-through since its launch in November last year. Sony Computer Entertainment group CEO Andrew House took a moment to continue the game console sales one-upsmanship to tell an audience at CES that PlayStation 4 has sold 4.2 million units to customers through December 28. The console launched in November last year. The announcement comes a day after Microsoft announced sell-through of 3 million units for Xbox One, which also launched last November, and a week after PS4.
