Nintendo's interpretation of a generation is certainly not about power but about how the player is experiencing the games. In other words the interaction bits.
NES: D-pad, 2 buttons
SNES: D-pad, 6 buttons
N64: Analog stick, 4 player ports
GameCube: Second analog stick(C-stick), GBA Link
Wii: Pointer controls
Wii U: Wii U pad, Asymmetric play
Switch: Joycons (also linkable to Lite)
Gameboy: D-pad, 2 buttons (same for Color, so same gen for Nintendo)
GBA: D-pad, 4 buttons
DS: D-pad, Touch controls.
2/3DS: Circle pad.
So I fully expect Switch2 to again have something new about interaction with the player. No idea what it is. Else it would be a new member to the Switch family eventhough more powerfull (see Gameboy and Gameboy color).
