(prediction) The Switch won't see any hardware revisions/variations in its life-cycle whatsoever

[KungKras]

Disagree.

Switch was made with an old semiconductor process to make it cheaper, but that makes it consume more power than it has to.

Nvidia could easily make a Tegra chip for Swith a newer process and thus much better power characteristics once these processes become cheaper, so we are going to see Switch revisions with much better batterylife in the future.
