as I and some were saying, Nintendo switch will be here to stay, how long is anyone guess. A new successor before 2023 doesn’t seem likely at all. Anyways....... here is the article

Nintendo’s next game system will bring forward the unique elements and learning experiences of the Switch.

This is a woolly answer, for sure, yet Nintendo isn’t one to showboat. In its 80th Annual General Meeting of Shareholders, an investor suggested that Nintendo should surpass the “limits” of a TV or an external monitor for their next console. Nintendo president Shuntaro Furukawa and director and senior executive officer Ko Shiota replied by praising the Switch, and saying that whatever is next for Nintendo, it would springboard from the successes of this console.

“Our current generation game system, Nintendo Switch, has entered its fourth year since launch, but its momentum is increasing,” stated Furukawa. “We believe there are two factors behind this. First is the existence of two hardware configurations with different characteristics, in Nintendo Switch and Nintendo Switch Lite. The second factor is that Nintendo’s development resources are concentrated on developing content for a single platform, Nintendo Switch. We want to extend the life cycle of Nintendo Switch while maximising such advantages.”

Extending it also allows for more chance of new features Nvidia comes up with in their tech to be included as well I can see the Switch doing Gameboy numbers at this point.

Other applications besides TV screens and external monitors?!?!?! PLEASE make an augmented reality windshield for cars, Nintendo! Turn driving into a video game fun for the while family!

Score points by performing tricks!
Time trial mode, see how fast YOU can get to work while dodging Pokémon!
Shoot turtle shells at your competition.
Achievements such as: hit 200 kilometres per hour, won 10 consecutive races, and the classic escaped the police.

Also, get The Weeknd to license the game. It will be HUGE!
Blinding Lights, the video game, available for vehicles everywhere!

Nintendo has the opportunity to revolutionize how we drive, Weeknd’s Blinding Lights, transcend all you thought you knew about video gaming with this Augmented Reality experience.

Or they could do another sort of Wii Fit health pack thing.

I really hope instead of throwing a bunch of gimmicks or oddities into the next platform that Nintendo just keeps it a mostly straightforward follow-up to the Switch. Just give me better specs, a better OS, better online, Switch backwards compatibility, and I'm golden.

2022 is still my guess. Maybe holiday.
Spring 2023 is the latest I can see it getting release.
I also expect Nvidia to impress us with the advancements in the mobile tech department for the next device, surprising us even more than with the current Switch.

Please don't name it the Switch U

you are sick, nintendo will never do achievments!

Great to hear the Switch will have an extended life cycle.

I hope a good Strategy RPG releases for the console, before it gets replaced.
