And of every five PlayStation 4s Sony sells, Layden says one is a PlayStation 4 Pro, a laudable achievement given its $100 price premium, enthusiast target demographic and the nascency of the 4K television market (where it's real allure lies).
"It is way ahead of our expectations," adds Sony global sales chief Jim Ryan. "As with PSVR, and I suppose in forecasting these things we haven't done a very good job, the product is in desperately short supply. So that's one-in-five under severe constraint."
"All of the rumors of the demise of the console are very much premature," says Layden. "In fact if you're watching [sales tracker] NPD for PS4 and Xbox One sales, you put those together and console gaming has never been as big and vibrant as it is right now. And that's just here in the States." Zip across the pond, and the story tilts further in Sony's favor. "It's been pleasing that in North America, we've been 2-to-1 against Xbox," says Ryan. "But in Europe, it's really been fortress PlayStation by at least 3-to-1 in unit sales."
"It's also the breadth of type of games," he continues. "And once you get up in the heady heights of 100 million units, you're talking of a different audience altogether, where having this range of stuff like Detroit: Become Human and FIFA and Call of Duty and Star Wars, it makes the job a whole lot easier."
