Yeah, the rumour isn't about a stationary console, but with the hardware revision likely precipitated by a die shrink of the SoC, it felt worth considering what options that gave them for other hardware.
The issue with using a Pro model to try to keep up with the next gen PS and XBox is that they'd have to allow publishers to release games which only ran on the Pro model, which I don't see happening, at least not 2 years into Switch's life. Besides, it would make more sense to release such a device after PS5 & the next XBox, when they would have a better idea of what to target, and could benefit from a move to a 7nm/5nm manufacturing process.
This new model next year would be 944GFLOPs (if Foxconn leak's Switch clocks was in fact this device). That would allow developers to release 720p current Switch games and simply allow the more powerful Switch to run those games at 1080p. A shrink to 16nm would allow a 512 cuda core GPU to run under 3 watts at 921mhz.
It's also too early for a Switch 2.
Switch "Pro" coming November 2019 is about 33 Months after the launch of the Switch, PS4 Pro is 36 Months after PS4's launch. I don't think it's too soon to see an upgrade, but I do think it's too soon to see exclusive software, however I don't know if Nintendo would allow 3rd parties to offer Streaming versions on current Switch models, or simply just allow them to run worse, it's not like every game on the Switch is a solid 30fps or 60fps, some games don't run that well and this could continue with a Pro on the market.
I was going to quote half a dozen people above me, this person has it right:
If they bring a new Switch model ca. every 3 years that wouldn't be as much of a problem, they wouldn't have to counter PS5 in 2019. PS4 will still get games for a while and at least in japan probably most of the games (and many games will be made with the old Switch in mind). It would be to not look too outdated and for fans that want better tech and that it doesn't fall behind smartphones.
At least Iwata compared NX to Smartphones that have more flowing transitions. It's also possible it will only be a revision with minor changes, but i see that as a risk too. At least Nintendogames should be able to maintain native resolution on the screen. It's like Nintendo makes most of its games with stronger hardware in mind.
Releasing a performance refresh every 3 years, following next year's model. Would allow Nintendo to do exactly what Iwata said they would do, move away from hardware relationships with their customers and move to an account based platform. You buy the Switch "Pro" and sign in on your Nintendo account and you have all your games and Nintendo Online right there.
Nintendo releasing a Switch 2.0 in 2022 wouldn't be a new platform, your current Switch would play many of the games, but the Switch Pro and Switch 2.0 might be able to play games that Switch can't (in 2022+). This is far better than Nintendo just releasing a new platform in 2022 that completely invalidates the current one and all (hopefully) 100 Million+ Switch users.
As for
4K, I don't think it would be a bad idea to launch an optional 4K dock in 2021, they could match PS5 and XBnext with some sort of 9TFLOPs+ GPU. The reason they would go so high in power is because you'd want to support 4K on the 2022 model, and that model would likely be 1024 cuda cores @ 1.1GHz (when docked) to reach 2.253TFLOPs, and run 944GFLOPs when portable.
It's not hard to see Nintendo go this route if they planned it all from the beginning and comments from Nvidia about a 20 year relationship, does seem to sound like they talked about this sort of progress for the platform, and I point out why I think that:
Switch originally was designed with a 307.2MHz portable clock and 768MHz clock. The relationship here is that the portable version of the current Switch, would run games at 720p and when docked, it would have enough GPU power to hit 1080p. Sadly 307.2MHz wasn't enough to run Zelda and other Wii U games at 720p without a dip in performance, this was only 157GFLOPs vs the Wii U's 176GFLOPs, so Nintendo upped the performance to 384MHz (196GFLOPs) but they couldn't match the ratio of performance needed when docked thanks to heat and throttling of the X1 chip itself. We've seen the Switch crack and battery expand, and while that is currently happening to a few (don't know the numbers and don't mean to make it sound small) customers, it would be much more widely spread if Nintendo ran the Switch GPU at 1GHz.
This isn't 100% the way they are going, there is a chance that this next model is just a 472GFLOPs docked performance chip, that would allow it to hit 1080p more regularly on the current lineup of games. I do think that Nintendo has to release the "Pro" Switch before the PS5 and XBnext hit the market, so that 3rd parties have a performance model to target with games that are cross gen in 2020 and 2021. If you don't have 10 Million+ customers running on that model, when you do release a new more powerful device to catch next gen multiplatform games, you'll be ignored until it's a hit. If you release a Pro that can also play these cross gen multiplatform games at 720p, that gives developers a reason in 2022 when they drop PS4 and XB1, to develop software for your system.
Current Switch users will continue to get brand new games for the next decade, but it might not get everything anymore after 5 and a half years, and I think that is fair. Streaming titles might very well be the future, and in that case, the Switch might always have a path to play the newest high performance games, but it's unrealistic to think that new more powerful devices wouldn't also be released.
So yes Thraktor, 2022 and 7nm+ is a better time to match next gen consoles, I just think that a ~1TFLOP console should still be able to receive cross gen and even next gen games at 720p (even if dynamic resolution is applied) and is a healthier and less risky transition to betting everything on the Switch 2022 device to also be a hit, when it completely breaks compatibility of everything behind it. Not doing that, would bring forward the platform in continuality like Iwata suggested 3 years ago.
