What will sell more, Animal Crossing Switch or Pokemon Sword/Shield?

I think that Pokemon will sell more out of the gate, but that the annual or bi-annual releases will cut it's legs shorts. Sun and Moon seriously could have outsold Diamond and Pearl if not for Ultra Sun and Moon. Animal Crossing will sell more than Sword and Shield lifetime.

I dont really understand this line of thinking.

Pokemon Diamond/Pearl & Black/White sold more than Animal Crossing: Wild World on DS and Pokemon X/Y & Sun/Moon sold more than Animal Crossing: New Leaf on 3DS.

Annual/bi-annual releases of Pokemon did not prevent it from outselling Animal Crossing on DS or 3DS so I dont see why that would change on Switch.
