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

[fatslob-:O]

I almost agree with OP, revisions are going to become less frequent with the Switch ...

Transistor technology progression is slowing down ... (less chances to upgrade the chips)
Big form factor ? (how much bigger does the Switch need to be ?)
Non-portable SKU ? (effectively kills one of the selling points of the platform)
