New Super Mario Bros. U Deluxe is the latest previously released Nintendo game to find a fresh home on the Switch. It's heading to Nintendo's new console on January 11th, 2019, throwing New Super Mario Bros. U and the Luigi-based platformer New Super Luigi U into the same package.
New Super Mario Bros. U was a launch title for the Wii U. While the game was decidedly fantastic, the Wii U was a flop. Launching on the Switch, which is selling like wild, introduces the game to a rich new lineup of players.

The full game is heading to Switch and it's getting two new characters along the way, Nabbit and Toadette. Nabbit doesn't take damage, while Toadette can transform into Peachette and execute double jumps.
Nintendo announced New Super Mario Bros. U Deluxe during the September 2018 edition of its Nintendo Direct live stream.
