I look at [PS4] Pro as more of a competitor to [Xbox One] S than I do to Xbox One X, claims Spencer. This is a true 4K console. If you just look at the specs of what this box is, it's in a different league than any other console that's out there. Spencer points out 40 percent more GPU speed, more RAM, and the speed of storage as the advantages of the Xbox One X over the PS4 Pro, but he also knocks Sonys methods for getting to 4K resolutions with some of its games. When I think about techniques to somehow manufacture a 4K screen like what some other consoles try to do, this is different than that. Spencer also says he expects the majority of consoles that Microsoft sells next year will be Xbox One S.
Finally, Spencer addresses the lack of first-party game announcements during Microsofts E3 press conference. Microsoft had plenty of big games to show, but in terms of announcements it was only Forza Motorsport 7 as a truly new triple-A title. Spencer believes Ori, Super Luckys Tale, and Sea of Thieves serve as solid announcements, but he admits he has been heavily focused on hardware over the past few years since taking over the chief Xbox role. I do think we have an opportunity to get better in first-party and to grow, says Spencer. We've got great support from the company to go do that.
Spencer also notes Microsoft has signed some things we havent announced but that its too early to build hype about.
