Electronics giant Sony today announced earnings for the period ended December 31, showing slowing PlayStation 4 sales. For the quarter, Sony shipped 9 million PS4 consoles, which compares to 9.7 million during the same period last year.

In October, Sony announced there were 67.5 million PS4s shipped, so with the 9 million more added in this earnings report, that comes to 76.5 million as of December 31. By comparison, the PlayStation 3 sold more than 80 million units worldwide, so the PS4 is closing in on that.
