You guys are not taking into account the fact that the COVID-19 is gonna have a huge impact in the economy of many countries. The IMF (International Monetary Fund) forsees consequences of a magnitude not seen since the last international crisis (the great recession of the late 2000s). In fact, it could easily be even worse than that. Some people are claiming it will be similar to the 1929 crash (although that seems a little far fetched to me...). Many people are gonna lose their jobs, prices of necessary goods are gonna increase and in general, people will have less money to spend in unnecesary things like videogames.
Now the Switch (and the videogame market in general) is doing great because the consequences are still to be felt and being always at home, entertainment products are in a rise. But when everything is set and done... I think sales are gonna take a noticeable hit.
A bad economy isn't necessarily bad for Nintendo. If the demographic that buys consoles isn't going to the pub/bars/clubs like now then Nintendo games are probably the best and cheapest $/hr form of entertainment.
I wouldn't want to be releasing a new expensive console any time this year though.
Don't Play Stationary 4 ever. Switch!
