If Nintendo would have released a more classic high-end console similar to the PS4 and X1

Would've been ignored just as badly by 3rd parties as Wii U currently is.
They went for that approach with GameCube, and it was their worst-selling console ever.
Wii U could've taken off big time, had Nintendo provided the appropriate games that would speak to consumers. Alas, they didn't, so it went downhill fast.
