Given that Wario, Waluigi, Donkey Kong and Diddy Kong have all now been found in a game that was previously only limited to the most 'safe' main series characters and styling?
Personally, I'm optimistic this may be the case. After all, Daisy went from being a spinoff only character to appearing in Super Mario Run, and Toadette has gotten a lot more attention recently with Mario Odyssey, New Super Mario Bros U Deluxe and Mario Maker 2.
So perhaps Waluigi may make a similar transition. Maybe with Wario himself coming back to the main series too, like in Super Mario 64 DS.
What do you think?
