Honestly there is no benefit to do small iterations.

Nintendo are on a winner with the switch they should hang out as long as possible before they release a switch 2, Even if its 3-5 more years.

They need to wait for technology to advance far enough where they can somewhat bridge the gap slowly to Sony and Microsoft. They can't keep playing catch up all the time with mini jumps. Only jump to a new system early if a system fails, like the WiiU.

PS5/XBOXXXXX will be what 12TFLOPS each? What benefit is there to release a switch in 2021? If wont even come close to the TFLOPS. PS4 Pro is what 4TFOPS? what could Nintendo possible release in 2021 that would even match that from a portable/docked perspective? It is a waste of time disturbing a eco system that is functioning. 

Exactly.

2021 will probably just see a premium Switch for people who want the best Switch experience and don't mind still buying a full priced Switch years after its launch. OG Switch will be discounted and Lite will be cheap for portable-only players. Then probably in 2023 Nintendo should be able to release a Switch 2 that is a significant upgrade that can at the very least run Pro/X games without a problem.

In 2022 it should be very easy to surpass the ps4's ram and cpu while also matching the x1x's gpu raw power in docked mode.

No dude it's not caring about companies it's acknowledging that a company has to do what they need to exist first before adhering to the minority on a forum that's how reality works companies aren't out there to fulfill every little daydream someone has they're operating a business with the aim of staying around for as long as possible and you know what that means not taking any unneeded actions that yields little to no return this is why the people you and him are harping on about barely even matter as far as Nintendo is concerned because that approach has no significant benefit for them.

Your Switch lite comment highlights you not only didn't read prior posts as I used it as an example of why the pro model is less likely but don't really understand why it was brought out it's an sku to sell more than one Switch to a household like what portables have done for decades OG Switch is viable for that as it's designed to be a console in the house so the Lite is there to cover that option the Lite actually has a business application to it being around the premium model you and some others are touting doesn't it's far deeper than being a choice like you think. This is why the Lite has had an impact and the likes of X1X didn't the former has fundamental reasoning for its creation the latter didn't and is just a choice for a select group of people who have little to no impact in the grand scheme of things, the difference this makes is that the choice doesn't give people a reason to buy it while the former does i.e have an extra NS in the house for the kids or partner to play for themselves.

To put it simply for anyone when you speculate what a company should do you have to look at it from the company's perspective because that tells you more about whether it makes sense for a company to do a said action.

With what exactly? What would the portable mode run at? 

So you think that just because the situation on the market hasn't changed in favor of Microsoft, they haven't benefitted from releasing One X in any way from business side of things? Okay, then

Just like the switch, everything will be the same except for the gpu being downclocked to 25-40% (depends on wheter nintendo uses a 1080 or 1440p screen).
