While 20 mil is higher than most Pokémon games do, judging by Sword and Shield, the Gen 9 Pokémon games are a safe bet (and they'll definitely be on Switch).
Other than that I can only see MK9 reaching that mark, but I honestly think they might save that for the next console (maybe a launch title?) since MK8DX is on track to beat the franchise record, despite being a port.
