Weren't there officially reported cases in China back in November of 2019? And I know places in the USA, before we even were thinking Covid, had a high amount of people with worse-than-normal-flu conditions, such as Arkansas, also dating back to November 2019 I believe.
Anyway, my point is that there were probably a decent amount of people that saw the writing on the wall and began isolating more even back to November/December 2019, let alone January/February 2020. Certainly as we got more shut down that helped more for sales, but there were people freaking out about the virus well before the CDC and governments started, and freaked out people staying home a lot more need things to do to keep their sanity.
Let's forget that you still have zero explanation for why a killer app like Animal Crossing would otherwise fail to drive up sales yoy, and the rising baseline going into 2021... your explanation for the Switch being up yoy in Jan and Feb is because the COVID panic actually began in November 2019, it was just in Arkansas... and they knew about the lockdowns and decided by the hundreds of thousands "Gotta get a Nintendo Switch!" I didn't realize Arkansas was the most cautious place on planet Earth and the one Southern US state not listening to Trump's "There's only 15 cases of Cheeyaina flu, and soon there'll be none."
Come on! Do you really expect anyone with functioning braincells to buy that crap?
