So... something big 'apparently' appears to be coming from Nintendo

That's precisely how nVidia's current external gpu offering (Razer Core) works though : via USB-C/Thunderbolt

And since it's only an extra Tegra X1 rather than a full GPU it's already a lot leaner of a setup than working with a GTX1080 in external form.

So it'll work fine - it's a solution nVidia has worked on for a long time already.

No, that's NOT how nVidia's current external gpu offering (Razer Core) works!

It doesn't combine the internal and external GPU. It is switching the internal GPU off in favor of the external and they don't have to sync.

The Razer Core also uses the Thunderbolt 3 double port protocol: http://www.trustedreviews.com/reviews/razer-core

The Switch uses USB 3.0, which is a completely different league: https://www.ifixit.com/Teardown/Nintendo+Switch+Teardown/78263#s156423

The Drive PX 2 which connects two Tegras on one board has a bandwith of over 50 GB/s (400 Gbps)... that is also "a bit" faster than the 0.625 GB/s (5 Gbps) the Switch can (theoretically) reach:

 

Congrats you are right. I was wrong.

Excuse me for not knowing the precise difference between the Switch's USB type C port and Thunderbolt.

Nitty gritty teardown differences aside, I see a physically similar port and plug and pretty straightforward use-case nVidia could leverage to push more products through Nintendo. Makes me wonder if all they had to do was upgrade it to a full Thunderbolt 3 port to make this a possiblity why they wouldn't go for it.

Conceivably if the Switch USB C port was indeed thunderbolt 3, wouldn't *you* see it as a possibility? It likely had to be considered during the Switch's development. Devil's advocate here - Perhaps they opted for a custom route with a similar outcome?
