Oh, they could most definitely get new halo elder scrolls, and fallout games earlier than every five years if they go ahead and let studios make spinoffs like everybody has been asking for Hell they have three studios that could make a fallout game Bethesda in exile and obsidian
I don't really get the Xbox plan here. Even trying to "accelerate" things, you are not going to get a new Halo or Elder Scrolls or Fallout sooner than every 4-5 years. There is still no hard and fast reason to get a console with PC and cloud available. The next actual console is going to be hugely expensive anyway barring significant changes.
The most vocal Xbox fans on here cheerleading everything already have a console and Game Pass, and the ceiling for that subscription service is hard to break through, much less making up the losses from the 50% hike. I don't see the vision.
