I believe more than ever they are taking the PC gaming route where xbox owners will be able to upgrade when they like to play games. This way they can have the cheapest system and the strongest system at the same time. For example, I think the xbox scorpio will be able to play ps5/xbox two games just at a lower resolution/textures. Unlike the xbox 360 and xbox one difference it won't be as huge because this will only be a 3 year console difference instead of seven. Microsoft UWP and directx 12 allows automatically scaling for what works best.
