my prediction is that switch 2 will have an unfixable overheating issue on launch and will have the worst battery life of any nintendo handheld until they fix it 2 years later 500%

depends on what do u want, the wii u has very few games, but IT EMULATES EVERY NINTENDO CONSOLE THAT CAME BEFORE IT. But the switch 2 will have NEW games! so if u wanna play old games, u should go with the wii u, if u wanna keep up with the new titles, u should get a switch 2!

if you already have a switch, get a wii

switch 2 may have vidmiio, and a lot of sources say it will be a lot like a wii U UI wise, but it will cost like 4 times as much not counting games
