Don't think of it as a Switch 2, any more than the Wii was a GameCube 2, or the NDS was a GBA 2.
That said, I personally think the Switch was a realization of what the WiiU tried to be: blending handheld and console, exploring motion controls, and solidifying online play with titles like Splatoon and Super Mario Maker.
The Switch itself experimented with VR with the Nintendo Labo headset, bringing VR modes to Super Mario Odyssey and Mario Kart, Smash Bros and Breath of the Wild.
They really could have pivoted strongly into VR, since the biggest barrier -- the hardware buy-in -- was already out of the way.
I wouldn't be surprised if the next console picked up where the Switch left off there.
