From Phil's lengthy interview -
Next fall it will be joined by yet another Xbox One, codenamed Project Scorpio. More powerful than the One S, Scorpio will operate at six teraflops, powerful enough to play both 4K-native games and virtual reality experiences (with the addition of an as-of-yet-unknown VR headset). According to Spencer, the improvement between Scorpio and the current Xbox One will be immediately noticeable. "I actually think the upgrade to Scorpio in terms of visual fidelity will feel as dramatic of a change as we’re used to seeing in new generations," he said.
But one of the most significant initiatives doesn’t revolve around a single console, Spencer said — it touches all of them. For decades console gamers have been faced with a persistent problem: when you finally upgrade to a new device, you’re essentially starting over from scratch, building up a new library of games. I can still play my dusty old copy of the first Diablo on my new PC, but apart from a few platforms that offer backwards compatibility, console games live in one console generation. Microsoft has slowly been adding Xbox 360-game support to the Xbox One, but now it plans to radically expand that initiative. Moving forward, Microsoft wants to bring the PC approach to consoles, treating all Xbox One games the same: they’ll all work no matter which iteration of the hardware you own. The next Halo will look better if you have Project Scorpio and a new 4K television to take advantage of all its capabilities, but it will still work on your current machine. "The idea is that wherever we are from the 360 generation on," Spencer says of the ability to carry over your library to new devices, "we’re investing in Xbox Live and content so that as you upgrade the experience moves with you."
Spencer says he expects new games will continue to work on older consoles "for a long time." And while I may technically be able to run the latest Xbox One games on my original hardware, that doesn’t mean I won’t be looking at the splendid 4K visuals on Project Scorpio with envy. But Spencer believes that choice is the key factor to this paradigm shift.
"What we’re saying is that we’re going to ship Xbox One games, and those games will run on Xbox One, run on Xbox One S, and run on Scorpio," he explained. "Am I going to run games in 4K on the Xbox One that I bought? No, you’re not. I’ll say the same things that I say to my 360 customers today: you love what you have on the 360, keep buying and playing games on your 360. Yes, I agree that there will be some people at the front end that will say, ‘Hey, I always want the latest and greatest,’ and for those people the upgrade cycle could feel shorter. But I’m not going to force that on you. I’m going to let you know that you get to make the choice."
