Pokémon > Smash Bros > Animal Crossing.
(This is assuming that we'll get a new mainline title of each next year, which is not very likely.)
Monster Hunter World Ultimate would be a big system seller in Japan, but I doubt it will ever be released. Dragon Quest and Yokai Watch will be minor system sellers in Japan.
New IPs and Metroid won't be big system sellers, since people who'll buy them will mostly be people who already own a Switch.
