>>713554094160,636,885 PS2s manufactured from January 2000 to March 2013 when it ceased production
Sony places sales at "over 160 million" since obviously, manufactured =/= sold
The original Switch is sitting at ~152.12 million (as of March 31st, 2025, 8 years + 4 weeks of sales), meaning it has to sell ~8,516,885 units before ending production to completely overtake the PS2. Last year, the Switch sold around 11 million units, and we know that it's going to be on store shelves with the Switch 2 as a cheaper alternative for at least 2-3 years. It also makes sense to keep making Switch games with Switch 2 Edition updates to try and cover both platforms.
The Switch has also never received a permanent price cut, only individual store sales. The closest thing to one was when the original Switch was replaced by the Mariko model, which has a better battery, but at the same price, and the cheaper, more limited Switch Lite.
