During the Nintendo Direct today, they opened up by showcasing Super Mario Maker 2. That's right, it's not a port, but a sequel to the the original Wii U game.
There's going to be brand new features such as the Cat Mario suit. Now creators can make levels that cater to this ability. Likely it will allow players to climb up walls and claw enemies, as well as use the suit's signature clawing abilities. Other new inclusions include enemies such as the ant trooper from Super Mario 3D World, and new interface options. There's even Luigi, who also appears on the cover of the game!
There are still more features in development, so expect to experience Mario like never before.
The title is expected to launch very soon. In fact, you can get your hands on it June 2019. For those expecting a port of the original, you're getting something better with this entirely new game.
