As of Now How much do You Expect Nintendo's 4 Major Evergreens to Sell Lifetime? (MK8D/SMO/BotW/Splat2)

[Paatar]

Assuming we will get Odyssey 2, new Zelda and Mario Kart 9

Odyssey - 17.2m
BotW - 14.3m
MK8D - 18.6m
Splatoon 2 - 11.5m

Odyssey 2 will probably sell better than 1. Zelda could very well also sell more.
Mario Kart 9 will sell more and I don’t think we will get Splatoon 3, especially if they just decide to keep giving us expansions even though they’ve stated updates will end at the end of this year.
