Remember that Sword and Shield are some of the fastest selling Nintendo games, ever—not just the Switch. It took Smash Ultimate a whole year to get around 17.7 million copies and that had stupid amounts of hype behind it.
Sword and Shield only needed a month and a few days to reach 16 million copies ( a feat that Gens 3 through 7 needed an entire generation and more to even reach around that number), and that was with a "huge controversy" behind it too.
