I think At this specific point MS has games coming this year. Halo 5, Gears remake, Forza, Tomb Raider, Fable legends, World of tanks will be coming sometime in the fall. Rare Games. Back catalog like Deadrising 3, Halo MCC, Forza 5, Ryse, Project Spark, Sunset overdrive, Titanfall, Just added backwards compatibility. Upcoming Phantom dust, Quantum break, Gears 4, Recore, Sea of Thieves, Scalebound, Crackdown And I'm sure a lot more.
At this present moment Xbox has the AAA games.
