Switch 2021 looks like it'll hit 10 million a week before Switch 2020! Amazing how well Switch 2021 has done at keeping up with Switch 2020 thus far.
These next few weeks might be a bit iffy though. I'm sure it will still be over 300,00 and maybe even over 350,000, but I don't know if it can keep hitting 400,000 for the next few weeks. Should be fine by the time E3 rolls around (assuming we get an awesome Direct), along with games like Mario Golf & SS HD in July (certainly more than what Switch had in 2020 during the same timeframe).
