During the Sony CES keynote, Sony CEO Kaz Hirai announced that as of December 28th, Sony have sold through more than 4.2 million PlayStation 4 units.
This comes just a day after Microsoft announced that it sold more than 3 million Xbox One consoles in 2013. Statistically speaking, this means the PlayStation 4 is selling out the Xbox One by 4:3 but the PlayStation 4 is available in 20 more countries than Microsoft’s console.
