The strategy described is just cross gen support. Not porting old games over although high quality remasters here and there would be cool (BOTW1/BOTW2 bundled), I'm just referring to development not being halted as developers try to get to grips with new technology. Nintendo described this as a problem with them moving to HD development and why the Wii U had a weak software line up. Switch 2 will start out the gate with great software support because it will share its libary with Switch, both Switches new and upcoming releases and more. All whilst boasting superior quality. PS4 and Xbox One early adoption was driven by cross gen games like COD, Destiny, Dragon Age, Watchdog, MSG4, FIfa, Far Cry 4 etc. It wasn't until year 2 developers started dropping 360/PS3.
(And this image doesn't even do justice to the res difference)
It amazes me how Nintendo continuously shows that weaker hardware and somewhat bad graphics do not affect their sales at all yet people keep insisting that somehow stronger hardware will be good for them. The problem we have is you are thinking like it's a PS or Xbox console and not like a Nintendo console. And we are thinking of it as a Nintendo console and trying to see how Nintendo will do things. Looking at their past, their own statements, their current leadership, etc we have no reason to believe that anything earlier than 2024 is even being entertained at Ninty right now. Of course situations are dynamic and things can change but right now I see no evidence of a switch 2 releasing in 2022 or early 2023 that will benefit Nintendo in any real way.
Regarding switch pro having exclusives and then being the main device or something, I don't see Nintendo doing that. The way the console market works and how people are hardwired is that hard resets happen. That means if Ninty or the other makers don't have the hardware reset, they won't experience the sales boom they do with a new console. Also any bad reputation from the base model carries over. Case in point is Xbox X and Xbox one. Xbox X didn't sell as well due to the reputation of One even though it was a huge update specs wise. XSeX is an opportunity to reset everything and create a new better narrative and hence sell more.
The marketing benefit of a new generation has been too beneficial for these companies. You have to make your new toy sound like a huge deal. Iterative updates like in smartphones and laptops just don't work that we'll for an entertainment device like a video game console. But if a company can market their product as a huge deal while being more iterative, well that's a challenge I'm not sure the big 3 want to accept just yet.
Also it's unfair to talk about the lazy pokemon game. It would still have the problems no matter the power of switch because they just didn't polish it enough and do enough to remove all the issues.
