I'm more certain that the X2 or possibly an even newer chip will used in Nintendo's next gen system with a Switch 2, the X2 would be too expensive and is too powerful in comparison to be a New 3DS upgrade, also they use two different architectures making game development a pain as one wouldn't just simply run on the other without any effort.

I'm pretty sure the X2 can run anything the X1 can, it specifically has a mode that lets you run X1 stuff just at half the electrical draw. 

I don't think it's all that expensive either, the Jetson X1 launched at the same price as the Jetson X2 that Nvidia sells (keep in mind these are *not* mass produced items, they are for a small community of developers). 

The X2 is simply the newer version, time progresses, new chips come out, the Tegra X1 is a 2015 chip, we're not in 2015 anymore. 

I think "Switch 2" will be the Tegra X3 or X4 (or whatever the equivalent is). That chip probably won't be here until 2019 or so. 

It'll be interesting to see what Switch revisions will be like. Hopefully the contract with Nvidia is favorable towards utilizing the new tech sooner than later.

I think for a iSwitch (6.2 in redesign), iSwitch XL, battery technology would have to improve so my guess is that will come after the Switch lite or mini.  Also, the first Switch model was definitely geared more towards the adult or older (teen+) gamer, so the next iteration should be for the cheaper 3DS crowd looking to upgrade (as it gets phased out).

As far as a potential mini design -  I suspect it would be something like the 2DS was (no hinge, no 3D), aimed at the younger crowd with less moving parts ie fused on controls  (so dock/controllers for external screen play  sold separate.).  Would essetially resemble a Vita or GBA. Switch LITE would be apropos, because it is cheaper and lacks the dock/joycons/grip etc. By next spring at the earliest, this type of model should be $199 to replace the 3DS shelf presence, but certainly less than $250.

Lets say spring 2018, we get Switch LITE, then for the holidays, or spring '19 adult Swichers get their upgrade with XL...

How long would Nintendo ride this until next gen Switch II?  Despite great success, could it be a shorter gen, i.e. 2021 or 4yrs,  like GBA (75 mil+ sold)?  If Nintendo sells through its new shipment of 16 mil BEFORE any revisions, or Pokemon, etc this could be another great hit, flirting with Wii level of success.

With 2 gens of Nintendo making 720-1080p games, I think they will move on to 1440 (portable)-4k dock.  I wonder what the minimum spec would be for Nintendo style games - maybe 2 tflops?  I know in 4 yrs Nvidia will have that tech ready, but as always cost is a big factor.  

I would be fine if they did revisions every year. Give me a 4G Switch with the ability to make calls, and texts, and I will buy one every year, and donate my previous one to someone that loves real games. Anything to take Android and iOS down a notch.

I plan to get a Switch this holiday, but I will be trading up or buying and handing down my previous Switch at every revision. Same will apply to Xbox and PlayStation going forward. I am 100% behind consoles and handhelds, and the new evolutionary hardware revisions.

Some battery tests on Switch show that the 20nm Tegra X1 based Switch runs at:

http://www.anandtech.com/show/11181/a-look-at-nintendo-switch-power-consumption/2

Docked: System consumes about 11 watts

Undocked: System consumes 8.9 watts at max brightness (so lets say 8 watts common usage, since most people don't play at brightness cranked to the max).

That means with a Tegra X2 you could be looking at theoretically

Docked: 5.5 watts consumption

Undocked: 4.4 watts consumption

Let say the LCD display consumes about 4 watts at high brightness ... that means to get docked performance with a Tegra X2 ... you consume 9.5 watts (5.5 + 4 watts for the LCD) ... that's almost the same as the current Switch uses in undocked mode.

So yeah lots of things would be possible with a Tegra X2.

I think you will see two new Switch models next year, with the current Switch model basically phased out. Nintendo will want a new model(s) anyway because usually the 2nd year of a console/handheld is when they really want sales to ramp up. 

Or they'll simply use that tech or any follow up tech in the switch successor for dead cheap.

You might be right, the DS phat sold 18 mil so it could be similar situation, once Nintendo fulfills their now revised order of 16 mil.  Tech heads keep saying how much cheaper it would be manufacturing 16nm vs 20nm chips so it makes sense all around.

I dont seeing Switch revision before end of 2018. earliest, and actual 1st revision will be Switch Mini just for handheld gaming, so that would be more like another device in family of Switch and not replacement instead of current Switch. Also I dont see stronger Switch in next 2-3 years.

Yup, eventually it's actually going to likely cost Nintendo more to keep making a 20nm Tegra X1 chip, because 14/16nm is going to be the standard for everything. 

This version of the Switch like the OG 3DS and Phat DS models will eventually be gone. 

3DS got its first revision (XL) at 17 months, I think it'll be the same for Switch. 

Current Switch is perfectly handheld and removing the right/left bezels will make the system even easier to carry around. 

I think THIS form factor is the future for Nintendo too, people need to get over it, the clamshell days are either over or going to be a minor part of Nintendo. 

This form factor is what you want for a *portable console* that invites people to gather around and play together and also offers premium gaming experiences (so you want that bigger display). 

In fact I would bet money that Switch revisions already physically exist in Nintendo's R&D labs, with a Tegra X2 inside of them. They're not some hypothetical concept that maybe is possible, I'd bet when Nintendo designers go to work, they are using those units and testing on them already. A year from now they'll be cheaper and easier to mass produce and suitable for public consumption so it'll just be an issue of when Nintendo wants to release them. The Switch you are using now as a consumer is something Nintendo finished up last spring if not sooner, their R&D is by now well past that, the main hold up would've been the Tegra X2 chip's availability, but that is available now to developers, anyone on this board could even get one, so Nintendo has likely had it for months.
