Nintendo's website(atleast in the US) no longer has a Wii U specific tab on the heading, only Switch and 3DS. Is this the final nail in the coffin of the Wii U? Worth noting the Wii U still does get some recognition under the "games" tab and the former Wii U page is still around in an extremely barebones fashion. It's almost as if this nearly 5 year old console never existed!
