Over 2 million. Probably about 2.3-2.4 million. That would have it finish 2026 about 4 million units short of PS2 which means beating PS2 in unit sales is going to be very tough.
It is so close to beating DS globally. It either has as we speak or for sure will before this fiscal year ends in March 31.
In a better economic environment, Nintendo could've priced Switch lower to get more people in the ecosystem and it would go past PS2 in the end (or already be there). A cheaper Switch probably could've finished around 162-170 million units even with Switch 2's popularity.
