I am honestly scared for whatever Nintendo is planning for a followup console or a pro version. But maybe not for the reasons you would expect.
There's a big downward trend I am currently seeing in quality as well as the quantity of the games for the Switch. And that's reminding me of the exact same situation as the late Wii cycle in 2010-2012 when Nintendo released a lot of half hearted stuff to the console and then boom, the Wii U came and flopped phenomally because they thought they could repeat the success by releasing a "powered up" console and people not understanding what the hell that thing is.The Switch already surpassed the Wii and I honestly fear they think the Switch is already done and then release the Super Switch or something like that.
And yes, when it comes to the games, the Switch lineup dissappointed me for the last two years. Sick of the Mario spin-offs (their quality also quite sucked), Pokemon games...yeah there's that, Zelda remake was meh, AC became quite out etc.
Like the only games of the last twelve months I liked was honestly just Metroid and Kirby. Former for sure is a question of preferences if you like these oldschool jump'run. Xenoblade is also on the horizon and of course Pokemon but looking at the rest of the lineup, there's only Splatoon left.
I am concerned with Nintendo's lineup and I feel there hasn't been enough heavy hitters the last few years, but I think the drought is happening for two reasons:
1. The pandemic. The last year I felt was satisfactory was 2019, then when the pandemic hit the Switch's library started to look very Wii U-esque. They may still not have fully recovered from the pandemic and there may be some projects originally planned for 2020/2021 that took a hit.
2. They're likely saving titles for next gen (we can pretty much assume this is the case for Mario Kart given what's happening there, it's highly doubtful that the Mario Kart team has just been working on Tour, Home Circuit, and the 8D DLC for the last 5 years). Part of the reason behind the Switch's success is that there were so many high quality games in its first year. Having BotW, MK8D, Splatoon 2, and Mario Odyssey (plus more, but those are the biggest successes) is an insane lineup that jump started the Switch out of the gate, and Nintendo may be trying to replicate that with next gen at the expense of the Switch's later years. To be fair, that would be a smart move, consoles tend to be more successful in their earlier years than their later years so they may actually be doing the right thing here.
Worth noting that behind the scenes Nintendo seems to be expanding their internal studios to get more games out:

If they can get some larger scale projects out more frequently to the point where they can have at least 1 IP that regularly sells about 5-10+ million (which will probably require experimenting with new IPs/spinoffs/gameplay styles because I don't think quite enough IPs have sold that much), then they should be fine in the long term.
As for the next gen Switch, they just need to make sure the system is decently powerful enough to keep getting decent third party support like the Switch and that they don't do anything so wacky that they have trouble explaining why gamers should want it. That was where the Wii U failed. History shows that they'll probably get arrogant about the Switch's success and it won't be as successful and I can see where they could potentially go wrong, but I'm not as sure the next gen Switch will follow the trend because I see fewer flaws in the Switch's design and Nintendo's long term place in the industry as I did with the Wii so I'm struggling to imagine how they could mess things up.
