China is getting things back on track, this is true, and it will help resolve Switch's supply issues at least, but China was only able to contain COVID-19 (for now) through extreme measures that the West don't seem willing to implement.
There's no way places like America or Europe are gonna have COVID-19 beaten as soon as two months from now. By the latter months of the year we may have reached the point where the current restrictions can be eased, but it still won't be completely back to business as usual until we achieve mass vaccination and herd immunity, and that's extremely unlikely to be possible within 2020.
Plus last year we had the gigaton bombshell of Switch's first mainline Pokemon game to supercharge the holiday quarter; there's no word yet on whether Switch will have any killer app tier games in the second half of 2020. That's not to say there won't be, there very well might, but it's all up in the air at the moment.
Nobody will beat COVID-19 this year, that has been said often enough. The virus is expected to be around for a few years at least. Regardless, life has to return to normal because otherwise the economical damage will do more harm to the peoples of the world than the virus itself. Hence why China is doing what it's doing because the economical threat is bigger than the still present virus.
China has managed to largely contain the outbreak through extreme measures; it really remains to be seen if the West can do the same, and if they can't, lifting the restrictions put in place to slow the virus will be sending millions to their death.
