Is nintendo the winner of the 8th gen or the 9th gen?

[Vinther1991]

The console gen term has less meaning now than it used to. But I have a check list with criteria I go through, if I want to determine which gen it belongs to:
In terms of horse power, which gen is it closest to: 7th gen
In terms of technology overall, which gen is it closest to: Tegra X1 is 2015 tech, so newer than 8th gen competitors, but not by much: 8th gen
Of competing systems, which launch dates is it closer to: 8th gen
Which gen of systems was it intended to compete against: Debatable, but probably 8th gen
Which gen of systems did it end up sharing most of its lifetime with: 9th gen
In terms of multiplats, which gen did it share most games with: 8th gen

The Switch is therefore an 8th gen system.

As for Switch 2 however:
In terms of horse power, which gen is it closest to: A bit more convoluted because of mid-gen upgrades, but looking at base console it is probably right between 8th and 9th.
In terms of technology overall, which gen is it closest to: Nvidia made a new costum chip, so 2025 tech: 10th gen
Of competing systems, which launch dates is it closer to: Seems PS6 and a new Xbox is not so far in the future, so 10th gen
Which gen of systems was it intended to compete against: Debatable, but probably 10th gen
Which gen of systems did it end up sharing most of its lifetime with: Hard to guess, but 10th gen seems more likely

Which puts Nintendo in the weird situation of having two 8th gen systems, a 10th gen system, but no 9th gen system. Then again they also had a 1st gen system, but none in the 2nd gen before releasing the NES in the 3rd gen.
