Switch should pass the DS in Japan sometime around the Summer of this year. As for worldwide that will take longer. I still think Switch has another 30m left in the tank for sales, but I don't think it will catch the DS this year globally.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
