Next year will for sure be over 20 million. Nintendo has plenty of moves to make next year to have a huge year before/as the new systems launch. I think price cut is obvious at this point, I could see a price cut mid-year during the slow time to give Switch a mid-year boost, maybe do that plus finally mark down some first party games with the Nintendo Select or whatever its called these days. BotW2 plus some AA games plus maybe even another huge seller on top of AC would easily do the trick for a 20+ million year next year. Nintendo would have to screw something up (like no price cut and a weak lineup) to not sell over 20 million next year.
