The one thing that worries me about Switch is the games they showed in the trailer, specifically things like Splatoon, Mario Kart, etc. looked basically just like Wii U games.
Even the new Mario game looked a bit better than Mario 3D World (considering it only has one character on screen instead of 4) but it didn't look like a PS4-tier game to me.
There's no guarantee Nintendo will use a fully clocked chip here. Even a Tegra X1 consumes up to 20 watts when pushing full load without an LCD screen to account for, that's pretty hot when you consider all the internal hardware of the Switch has to be inside a very small central space there and then also consider a large chunk of that internal space has to be taken up by a large battery.
My worry is Nintendo basically told Nvidia that something just a little better than a Wii U was good enough and that they focused otherwise on keeping the power consumption low. Seems like a very Nintendo-ish thing to do.
I'm not so sure we're getting like a 20 watt Tegra X2 (docked). It may well be some more akin to a downclocked 10 watt Tegra X2 (docked) and 5 watt (undocked).
