What most people don't realize is that the OP will have to create a new tier for Switch. It has SS for DS and PS2, but Switch will be SSS tier.
Switch is going to peak at about 30m this year. People keep looking for Switch sales to drop off of a cliff, but it isn't going to happen. Switch's sales descent will be fairly gradual. Not only does Nintendo plan to keep supporting the Switch (BotW2, Splatoon 3, Pokemon Arceus, etc...), but the number of titles on the Switch has increased each fiscal year so far. Even during COVID the number of titles released. Third party developers keep giving the Switch more and more support. It's also going to get more support this year than the last. There are so many new titles on the Switch, that it is going to take it a long time to stop selling completely.
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
