I'm very bullish on this issue. I don't think Switch will get anything that sells like Wii Sports, but it will have an unprecedented number of 10m+ sellers.
Games released in first 24 months:
Zelda: BotW
Mario Kart 8
Splatoon 2
Super Mario Odyssey
Super Mario Party*
Pokemon Let's Go
Smash Bros
NSMB U
I'm giving Super Mario Party a 0.5, because I'm not sure if it will cross 10m or not, so that is 7.5 total. I think there will be a similar number of first party games during the rest of Switch's lifetime bringing the total to 15. I also think there will be a few third party games that cross the line, somewhere between 3-7 titles.
Grand total: 18 - 22 total that sell 10m+
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
