Why though? That hardware obsession with the Switch is nonsensical. Games already run perfectly on the current hardware.

I wouldn't say "perfectly". 

The lead launch game, which is a Wii U port, suffers from heavy slow down in areas and some bad pop-in as well which breaks immersion, and that's a launch title. I would like the Zelda team to have the freedom to make a bigger/more intensive game if they want to, I think the current Switch hardware while pretty good would have some problems with that task. 

They'd likely have to scale back their vision if their vision is something grander than BotW, which it may well be. 

If you don't like the hardware, hey it's not like you have to buy it. There are people who like their iPhone 4 just fine, they don't have to buy an iPhone 8, but some of us want an iPhone 8. 

Isn't DLTOPS calculated for 8-bit integer, for Deep Learning aplications?

6.6TFLOPS (FP32) sounds insane for 512 core part...it would either mean core clocks of 6500MHz, if we're still going with classic 2 ops per cycle, or those cores can do at least 4 ops per cycle...and then they still need to run at 3000+ MHz.

The current Zelda has quite a bit of freedom and according to my sources runs like a 10/10.

The hardware struggles to run that game at times, and that's a launch game. If EAD has bigger ambitions in the future, they are likely going to have to scale them back. 

The 25GB/sec memory bandwidth is problematic I think for Nintendo in particular. Even the Wii U has a memory pool of eDRAM that's considerably faster than that, but going with the stock Tegra X1 made sense precisely because they can just swap in new Tegra chips as time goes on. 

Aren't launch games usually running worse than anything that comes after it?

And it's also a rather rushed port of a wiiU game that runs perfectly in 720p HH mode. The game improves a lot on Switch post patch, with the few slowdowns in HH mode all but eliminated and drastically reduced sowdown in docked mode. There's really only two or three environments in the whole game where slowdown happens while docked and it's not drastic slowdown either.

This shows that BotW issues are optimization issues, not hardware issues.

That said I could see a 4k ready Switch Pro release down the line, with improved battery life on the go and improved docked performance for 4k. Nothing that would fragment the user base or create revision exclusives though. Nintendo haven't really done that in a big way since the GBC. Even the new 3DS only has one exclusive so far, with a second one on the way.

I'd be cautious with the numbers provided by Nvidia, as some users have already said.

Also, Soundwave, if Nintendo went with an X2 in a Switch revision, the battery life wouldn't double. The processor is only one of the different components of the device, so even if the power consumption of it would be cut in half, the rest of the components would still use the same power, specially the screen, so the real world improvements would be quite lower than what you believe. Maybe one extra hour or so.

Still, the system is barely one month old. Talking about revisions and successors so soon is depressing.

I highly doubt that if anything going by how Nintendo operates they'll simply use the tech in the Switch successor in 6 or so years from now when it's cheap and viable.

going by how Nintendo operates? what does this even mean?

every Nintendo handheld has recieved a few revisions, why would Switch be different?
