Even if Miyamoto doesnt making some decisions any more, he is still with Takeda on strongest positions in Nintendo after Kimishima, and off course he knows about future Switch plans.

One revision, 6-7 years life span and maybe Switch mini. Thats all. In 2022-23 we will see new Nintendo console.

I don't see much in the way of performance upgrades and Nvidia seems to have failed to make Tegra successful in mass acceptance. The reason it was stated Nintendo got the Tegra at a cheap price was because of the failure of Tegra to sell well even claimed use of a stockpile of chips that Nvidia couldn't sell. The Switch is pretty much their only large success for a mass market platform. Most of the future plans for Tegra seem to involve moving towards automobile chipsets and autonomous driving. Future Tegra chipsets may not even be ideal for Nintendo they may even go for a custom chipset based on Tegra X1 with their own desired upgrades to remain 100% compatible with mk1 Switch.

I feel Nintendo are more interested in making Switch a better portable device long term rather than tiered performance levels. It's still very much possible Nintendo would ditch Tegra altogether in 5 years time and move to a completely different provider for a chipset. Nintendo have shown pretty much no loyalty to any one company in the past.

The's no competition in the portable industry so it'll have a 7 year life minimum we've gone full circle where they'll have a monopoly again like the GB days after blowing out the competition.

I am pretty sure Nvidia will consider Nintendo needs in future chips and that Nintendo will stick with Nvidia (Nintendo talked about problems when they had with everyone new generation, when they need to start from scratch everything because of new chip, and that they want to fix that).

Maybe, I'm just saying ... maybe just maybe a system that has already broken virtually every other "hardware rule" may not be bound by the conventional 1980s hardware upgrade path you think. 

What would a "Switch 2" even be? Just a Switch, with a better chipset .... so why even start from zero? A more streamlined continuing generation just with a hardware refresh in that case makes a certain degree of sense. 

Once they went with the hybrid approach IMO, all bets for anything else being "the same as the past" went out the window. 

6-7 year cycle isn't much different from the standard 5 year cycle. Adopting a cycle more akin to modern tablets/smartphones would be different though, and I think would suit the Switch well. 

I doubt this.
I basically think there will be a Switch 2, with newer chips (more power) inside soon, like 4 years from now.

We here talking about power, Nintendo don't pursuit power, I don't see what would be point of Switch Pro that has power on level of PS4 when current Switch has enough power for its purpose. Yes, I could see that for Switch 2 in 6-7 years, but for revision of current Switch in just 3 years, I just dont see it in any case. Also Tegra X3 for Switch revision when current Switch is using X1, not gonna happen, but it's realistically we can expect Tegra X2.

Nintendo will probably include something else new for Switch 2, but of course that difference will be bigger in any case compared to Switch and Switch Pro. Like I wrote, what you wrote for your Switch Pro (Tegra X3 PS4 tier performance), Nintendo would probably call that Switch 2, not Switch Pro.

It not point about "same as the past", but what makes sense. Expecting that Nintendo will make Switch Pro with Tegra X3 in PS4 tier performance in 3 years doesn't make too much sense, and I am sure that want be case, instead we will have Switch Pro and Switch Mini with Tegra X2 around 2019.

I disagree, 1-2 years more makes huge difference in Nintendo case. Like I wrote, look life span of 3DS and how Nintendo managed 3DS revisions, they probably aiming for something similar with Switch, and that's huge difference compared to Wii U, Wii and GC.

Switch something similar like 3DS will have few revisions that will extend Switch life, around 2019. we could easily have Switch Pro (1080p screen with same performance like in docked mode) and Switch Mini/Pocked (smaller, cheaper Switch for handheld play). There is no any need for Switch 2 so fast if Switch is selling good, but there is always need for revisions that offers different price points.

Basically this.When a revision happens, of a more powerful Switch, this is what Nintendo is going to do, not what Soundwave described.
