So we are wrong to question Nintendo's experience and research when they developed the Switch because they got it wrong with the N64, got it wrong with the gamecube, got it wrong with the Wii U, but got it right with the Wii. That's 3 consoles of 4 over a 20+ year period that missed the mark, but we should totally trust that Nintendo currently has its finger on the pulse of the gaming industry because they made the Wii. 12 years ago. Brilliant.
The same company also made: NES, SNES, DS, 3DS, Gameboy, GBA (and failures as VirtualBoy, GC, and Wii U, I think N64 wasn't a failure). It has 10 billion $ cash on hand, and was highly profitable almost every year based on production and sales of gaming related hardware and software and gaming related merch.
But please, do tell me how they are clueless when it comes to gaming hardware design.
Also, funny you should mention Gamecube, because it was exactly what "real" or "hardcore" gamers wanted - the most powerful console of the generation.
