If we want to consider technology, I'd say that this gen has only PS4 and XBO. Nintendo left standard home console market as soon as Wii U died. So Wii U is 8th gen and the last standard traditional home console of Nintendo. Switch is 3DS successor.
God bless You.
My Total Sales prediction for PS4 by the end of 2021: 110m+
When PS4 will hit 100m consoles sold: Before Christmas 2019
There were three ravens sat on a tree / They were as blacke as they might be / The one of them said to his mate, Where shall we our breakfast take?
