At the end of its life the Switch will have sold at least 30 million units and the PS5 6-8 million. The PS2 sold 21 million units in Japan. If the PS5 sold that much, the 9th gen would have numbers way beyond 50 million. For the PS5 and Switch combined to sell less than 28 million units would need the Switch to stop selling in half a year. The market in Japan is performing as good, if not even better than before the Switch launched. I believe, that the Seitch has a chance at surpassing the total sales numbers of the Gameboy at 32.47 million and the DS at 32.99 million. It's only halfway through its life after all.
