Spencer went out to say that they lost the most important generation to lose (XBOX One gen, not the current one. Corrected thanks to @Boldizzle ), and that they were going back to the drawing board to turn things around. They just hiked up the prices of Game Pass and the XBOX Series X. They also basically confirmed that there won't be any mid-gen "pro" model and that they expect the next gen to come in 2028. And now their plan to buy the industry is also failing.
So what's next? I doubt they have a queue of heavy hitting first party exclusives in the oven to maintain them until 2028. I'm almost certain that they expected to buy themselves some time by acquiring studios and turning their IPs into system-seller XBOX exclusives.
