Let's say PS5 sells around 600k+ this year in Japan, that would put its lifetime sales at the end of 2026 at at around 7,9M-8M. Switch 2 is now at 4M, so seems likely with those figures in mind that Switch 2 overtaking lifetime PS5 sales in Japan should happen around September-October at the earliest
I think Switch 2 will sell around 5M+ this year in Japan. PS5 could also have a somewhat bigger decline to maybe 500k+ or so sales in Japan this year which would make Switch 2 overtake PS5 a bit faster as well.
If my prediction comes true, that would mean that Switch 2 in 15-16 months on the market would overtake what took 6 years for PS5 to sell in Japan.
