I truly believe Wario Land is gonna make a comeback. People keep asking for it. And Nintendo has been bringing back a fair bit of Wario. Hell, they even brought back the Mario & Wario Snes game that most people didn't even know existed.
Agreed. Though it was still pretty damn cool to have him in 64DS. I LOVED playing the versus mode with my friends back in the day. Wario's special move where he grabs a player, spins them around and yeets them, was so much!
Waluigi making a short surprise appearance in a Ware game would be the best move.
I always thought he'd make a cool theme for the final stage, where he's sabotaging you by randomly making the microgames harder and longer and other stuff to keep you on your toes.
Also a fakeout where you beat...
