Microsoft is planning to create an Xbox ecosystem. The idea is offer a service more than a specific hardware. In this manner, Microsoft could release most of its upcoming Xbox One exclusives on Windows 10.
WPDang has published an interesting rumor. Reportedly, Forza Motorsport 6, Gears of War 4, Scalebound and Forza Horizon 3 (first mention of this game) would reach the Windows Store shelves alongside the Xbox One ones.
The last year, the company announced that Gears of War Ultimate Edition, ReCore, Halo Wars 2 and Killer Instinct will be available on Windows 10. Therefore, this fact (and the Quantum Break Win 10 ver.) reinforces this rumor. One for all, and all for one.
