If Switch 2 is coming out mid or late 2025 i think its a lock that Switch will surpass Playstation 2 sales, Switch sales will crater WW next year but as long as its the main Nintendo console it will still net higher sales than it would after a new Nintendo console is launched. So if Switch sells 10-11 million this year, it should have a decline of around 40-50 % next year to around 5-6 million sales. After that they would only need 2-3 million more sales to pass the PS2 which i think will happen.
