Sony has been making moves throughout 2016 to secure more of the gaming console space, with over 50 million PS4s sold, you could definitely say they're making the right moves.
Lead Architect of the PS4 and PS4 Pro, Mark Cerny was interviewed with IGN alongside Guerrilla Games' CEO Hermen Hulst and Hideo Kojima where he said: "I think one of the things you're seeing is just the benefit of focus on a single platform".
He continued: "You can know the technology down to the tiny hardware details and then take advantage of them in your engine. And that really pays off. I mean, I was sitting there this morning at the keynote at PSX 2016 and it's clear that Guerrilla and Naughty Dog have somehow found the button you push that makes more polygons come out".
Kojima decided on using the Decima engine for Death Stranding, the same technology that powers Horizon: Zero Dawn. The collaboration between Kojima Productions and Guerrilla Games will have "substantial benefits" for Guerrilla post-Horizon, which is due in February 2017.
