Pokémon Sword/Shield shipped 21.10m by March 31st. Lifetime sales expectations?

[Dulfite]

I expect somewhere between 22-25 million. 22 million if Arc is received well and feels like a high quality mainline game. 25 mil if Arc feels too experimental and doesn't have polish. The remasters won't impact the legs of Sw/Sh in my opinion, but Arc will one way or another.
