You get it.If that's true that is the dumbest name since, well Wii U. Do you want parents doing Christmas shopping thinking your new console is a new console or do you want them to think it's an accessory for the one their child already has?
Wii U really did sound like an add-on. Like, "64DD is to N64" as "Wii U is to Wii." Even if it's mostly the same design as the Switch, this new console really should have a unique name.
Nintendo does, in fact, learn from their mistakes. The turnaround time for better decision-making is the slow part.
