Nintendo's strategy isn't the absolute worst. They mostly just give new names to new console designs, with modifiers to specify next-gen-without-major-changes. So the SNES was a next-gen NES, the N64 was its own thing, the GameCube was its own thing, the Gameboy, Gameboy Color, and Gameboy Advanced were iterations on the same thing, DS, DSi, 3DS were all generation steps. WiiU was a next-gen Wii, Switch 2 is a next-gen Switch.

They probably should have called the WiiU the Super Wii or Wii 2 or something, but on the whole they've got a mostly coherent naming convention.
