While I see Microsoft leaving before Nintendo and Sony, I don't buy that Xbox Series X/S is their final platform.
Microsoft isn't Sega, they can lose oceans of money on Xbox and the parent megacorporation of Microsoft will still thrive. I'm pretty sure Xbox 360 was the era of Xbox where they lost the least amount of money relative to profits. Even then, they still lost a great deal of money.
Microsoft will probably try another Xbox strategy before bowing out. I even think after (or during) the time they leave Xbox consoles behind, they will have Xbox branded Gaming PCs. These will be for enthusiasts and sold at little to no loss (compared to consoles which sell at a loss for a while).
