PlayStation 4 has sold through over 70.6 million units worldwide to consumers as of December 3, 2017, Sony has announced. The figure brings total sales numbers for the PS4 closer to the 80 million benchmark it achieved with the PlayStation 3.

Sony did not, however, provide information on how the sales break down between the original PS4, PS4 Slim, and PS4 Pro, which launched in November 2016. In a press release, the company added that the strong sales of PS4 has had a positive impact on [PlayStation VR] which has cumulatively sold through more than 2 million units as of December 3, 2017.
