Sony released some new stats today detailing the progression of sales for its PS4 console and PS VR headset systems. The numbers that matter: 70.6M PS4 consoles, 617.8M PS4 titles, 2M PS VR headsets, 12.2M PS VR titles.

Things appear to moving along rather well in console land, where Sony is almost certainly winning the console wars with Microsoft. Microsoft hasn’t released unit sales numbers since January of this year when it announced that 26 million Xbox One units had been sold. In that time, Microsoft has released an updated version of the system, the 4K-playing Xbox One X. Sony released the souped-up PS4 Pro last year.
