Mattrick and his cohorts doomed Xbox One from the start and it can really be traced back to halfway in the 360's lifespan where the strategy was more focused on entertainment apps and Kinect than it was on games. MS got a huge blow to first party studios as well after losing touch with Bungie and Epic, and then killing their own internal studios like Rare. Now for their new console's exclusives they have to go and fund games from development studios (Platinum, Respawn, Insomniac) rather than relying on their own which is fine for the early years, but I can't say I'm confident at all that they will continue the current 1st party support halfway through this gen.
