Business Insider reports that during a session at this week's a session at the Game Developers Conference offered some more information from Microsoft's Xbox Advanced Technology Group boss Jason Ronald:
"First off, the Xbox One is going to get the ability to run those Windows 10 UWP apps later this summer, with the Xbox Store and the Windows Store getting merged into one. Furthermore, UWP apps are gradually going to open up over the course of this year to run the more advanced graphics settings that PC gamers demand."
Ronald also stated that developers could make a UWP-based game that just targets the Xbox One console
"Microsoft is working hard to make a range of tools and features available to make building games on Windows attractive, regardless of whether or not you're actually investing in the PC market, he says, with the goal of simply making UWP the best place to build games."
Microsoft is expect to reveal more information on how UWP apps will work on the Xbox One in two weeks at its Build 2016 developer conference on March 30.
