Will Wario Appear in a Mario Platformer Ever Again?

Like he did in Super Mario 64 DS back in the DS era? Or heck, even as a villain like in Super Mario Land 2 with his debut?

Or do you think the two franchises have been separated so much now that Wario is basically confined to spinoffs as far as Mario games are concerned?

Daisy debuted in a Mario Land game like Wario and she's playable in Wonder, so maybe.
