The original Switch is officially Nintendo’s best-selling console of all time after surpassing the DS handheld in lifetime sales. In its latest earnings release, Nintendo reports that the Nintendo Switch has, as of December 31, 2025, sold 155.37 million units since its launch in 2017, compared to 154.02 million units for the 2004 Nintendo DS.

Looking at the best selling consoles, ( https://en.wikipedia.org/wiki/List_of_best-selling_game_consoles ) there are some other interesting things too. Switch is already # 2 and Nintendo Switch 2 is too new so not much to see there, but when looking at PlayStations, PS5 (84.2 M units sold) is currently the least sold Sony home console, but should take over PS3 (87.4 M) soon enough. I think it will cross PS1 (102.49 M) too, but whether it can cross PS4 (117.2 M) sales remain to be seen.
If the rumours about delaying PS6 to 2029 are true, then it has good chance to take over PS4, but with the way the prices and economic condition are going, who can say what will happen.
