More than 1 million cuz there's pent up demand for Metroid and everything sells well on Switch. Less than two million because at $60 it's overpriced and about $30-$40 more expensive to plenty of similar games on the market.
If they launched it at $30 or $40 I'd have said over 3 million for sure.
Possibly all these numbers are low just cuz Switch is so popular. So maybe it does sell like two and a half million cuz of Switch multiplier, but woulda sold like 5 million if reasonably priced.
