I personally would love if Nintendo keeps Switch going into 2025 and breaks 160m. Cuz that means a bunch more big games are planned for the Switch. I am very ready to continue using my Switch for years to come, and honestly it doesn't remotely feel like Switch is getting to its later years yet - I'm still wondering when so many games are going to come out. Nintendo says Switch is in the middle of its lifecycle, I've had my Switch for 4.5 years and honestly feel like I could easily go another 4.5 years with it if that means they bring out all the games that I want on the system.
Switch is probaby the first system I've ever owned that just doesn't feel like it is getting old. Its hardware design is still as awesome as it was when it came out, it's got a great library and plenty of more huge games to come, and it is a portable with no competition so it isn't trying to compete with the latest console graphics so there isn't that feeling of like "oh it's falling behind compared to newer systems". I still think they'll likely launch Switch 2 sometime in 2024, but I'd be perfectly happy playing this thing until 2026. Usually around five years you can tell the user base starts thinking about the next system and looking forward to it, but it doesn't feel that way with the Switch, because everyone is just looking forward to all the huge/awesome games coming out for it in the future - Kirby, Splatoon, Mario+Rabbids, BotW2, MP4, and many more we are expecting.
I guess for graphics obsessed people who didn't like the Switch even when it came out they are very focused on Switch dying early and getting a more powerful system out. Of course they still won't be happy when the Switch 2 comes out if it is the same kind of system because it'll still be a portable which means less powerful than what a new console would be.
And for the graphics focused people who desperately want a new Switch now, they should realize that the later Switch 2 comes out, the better because that means it will be more powerful. Also with more power and DLSS tech to scale up resolutions nicely on the cheap, a later Switch will do a better job of getting AAA playstation/xboxSeries multiplat games than Switch did of ps4/xboxOne games.
