Couple of interesting things about this then ...
1.) It means Nintendo could technically if they wanted to release a Switch redesign as soon as even this year. Not saying they will do that, but we know the Tegra X2 (Parker) chip is readying shipment in like a month ... that chip can operate at the same level of a Tegra X1 at 1/2 the power consumption, which means a more compact Switch with say the right/left bezel borders cut off and a possibly bump in battery life would be doable basically right now. Of course they won't release a new model just yet, but it does like mean Switch revision is very likely I think next summer IMO. DS/3DS got their first revisions around the 18 month mark, I think Switch will be similar.
2.) A full-on Switch 2 could be made without much fuss either in a few years time. A Tegra X3 (Volta based?) would probably give you 1.2-1.5 TFLOP docked, and 2.5x less that undocked would be a nice sized upgrade and Nvidia is likely already developing this chip as they have been finished with the Tegra X2 design for a couple of months now.
It is still kinda mind blowing though that after all the fuss about NX it basically just turned out to be a Shield tablet with removable controllers as the big "surprise" though, lol.
