PS5 is really ramping up (its peak will probably be 2024), and Switch continues to sell spectacularly considering its age and lack of price cuts (but there are bundles on the way).
Xbox is being beaten even by Switch in Europe and obviously Japan. Xbox still has a lot of time to sell if Microsoft sticks to a 2028 release date for the next-gen Xbox.
