Sony/MS take portables or Nintendo takes home consoles?

[Pyro as Bill]

WiiU and 3DS were Nintendo's failed attempts at moving upstream from Wii.
3DS only had 3D because Sony and the rest of the movie industry were pushing it. Nintendo must have thought they'd struck gold when their R+D department told them they could do it portably and on the cheap.
The reason why Switch seems more like a proper sequel to Wii than WiiU is because it is. WiiU was a poor attempt at moving upstream and reclaiming the home console market whereas Switch is the perfect weapon. That's why it's so overpowered. I couldn't work out why Nintendo would use such powerful hardware and amazing graphics for a handheld but now it makes perfect sense when you consider what it was actually designed to do.
