To be fair, the Wii U did pretty good at launch. If "pretty good" means being outsold by every other system except the Vita and the DS in it's first 2 months, that is.
Seriously, people don't understand how much of a gigantic failure the Wii U was.
Don't talk bad about Wii U. Sure, Switch's first seven months already comfortably beat Wii U's first twelve months, but Wii U lifetime could beat Switch's first twelve months.
