The Tegra X2 or whatever its called, is supposedly almost twice the performance/watt of the Tegra X1.

So if you made a new "switch" on 16nm?, instead of todays Tegra X1 (28nm), it would be around double the performance (at same power usage).

393 Gflops -> 786Gflops.

Thats still less than half of the PS4.

Even 5 years from now,.... with a Nvidia Tegra X3? and maybe 7nm, I suspect it ll still be abit weaker than the current PS4.

You are talking about a five year span here. Tegra will likely not even be labeled "X-whatever" then. I suspect an "X3" would be long old technology, and the x-series analogous to the non-K/X series today. 

Again Tegra 2 had a max of 7 GFLOPS in 2011 and the X1 500 GFLOPS in 2016. Even if Moore's Law slows its pace for GPU technology like it has for CPU's (which is a wild prediction), it is unreasonable to believe that it will slow that much.

Switch's successor is going to easily be more powerful than a base PS4, and likely will match or exceed a PS4 pro.

Apples & oranges.

Tegra 2 was ment for smartphones. (0.3-1,5watts)

Tegra X1 is ment for cars. (10-20watts)

You cant really compair them directly because their at two differnt power consumption levels.

 

Nvidia:

2013 : Tegra 4 = 76.8 Gflops @4watts (28nm hpl)

2014 : Tegra K1 = 365 Gflops @8-10watts.  (28nm hpm)

2015 : Tegra X1 = 512 Gflops @15-20watts (20nm)  (shield TV uses 20-22+ watts when gpu is at max load)

 

These are big improvements over just 2 years time... however I dont think it continues at this rate.
