Nintendo moved some switch production outside china already to avoid the possible tariffs that never took place but were threatened. I assume those factories in southeast Asia countries produce consoles for mainly USA. However that doesn't mean components needed for switch produced in China might become harder to find due to China manufacturing taking a nose dive in January month due to concerns about the virus.

I'm about to get a switch in less than month so not worried. As for PlayStation and Xbox fans... Good luck if this goes longer than a few months. If I were you I'd tell them to get back to work. They already had enough time off allotted to them to cover rest of year.
