According to the details shared by World of Tanks developer Wargaming creative director and executive producer TJ Wagner, by 2019, PlayStation 4 and Xbox One combined sales (worldwide) will be 108 million units, with PS4 leading the way with 69M units sold. These figures were first made public at Game Developers Conference presentation (slide) by TJ Wagner.
Another slide from the presentation claims there are 36 million active PS4 consoles in the market today, ahead of an estimated 19 million Xbox One systems. Wargaming got its numbers from sources including Superdata, IDG Consulting, and IHS, so bear in mind that these numbers don’t come directly from the source.
In terms of official numbers, Sony said in January that the PS4 had sold nearly 36 million systems worldwide. Microsoft does not share Xbox One sales figures, but it was reported that, months ago, there were around 18 million active Xbox Ones in the market.
In 2015, Xbox boss Phil Spencer said Sony’s lead in the current-generation console sales race was so large that he was unsure that Microsoft would ever be able to catch up. It doesn’t sound like Microsoft is stressing too much in its No. 2 position, either. “We’re not motivated by beating Sony, we’re motivated by gaining as many customers as we can,” Spencer said at the time.
