Few things to keep in mind.
Gamecube launched after the successful PS2 and had competition from the newly launched Xbox as well.
Wii U launched before both PS4 and XB1 were on the market, but off the back of a successful Wii. Wii U lost a lot of third party support early on before PS4/XB1 even.
Gamecube lost a lot of third party support after a couple or years or so.
Gamecube launched at $199 and was $99 after just 23 months (Hence the boost in sales then)
Wii U launched at $299, and outside of a couple of promotional offers, has never been less than that.
Here is a look at Nintendo Home Console Hardware & Software Sales from NES to Wii U.
