ACNH & MK8DX are well on their way to surpassing MK Wii this year. I don't see ACNH surpassing MK8DX though.
Ultimately, depending on how long it takes until a Switch successor releases (hoping for Holiday 2025), I could actually see MK8DX reaching sales north of 70 million. Possibly even surpassing Wii Sports (at least if you include MK8 on Wii U). I could see ACNH reaching about 60 million in its lifetime.
They'll fall off pretty quickly once the Switch successor gets its own MK & AC, which I could see happening within the first year of the successor.
