I'm hoping the Mario brand evolves to be more akin to the Mario Movies' style.
I still think a lot of Mario games, especially ones like Paper Mario and M&L that have their own distinct style, should stay the same. But when I watch the movies and/or look at the Mario Galaxy poster, I see a proper, true evolution of Mario that I really wanna see in the future for some of the games.
Does it sound hard to evolve? Yes, for both Nintendo and the fans, but my hot take is that the Mario Movies basically look like Mario games like 2-3 generations from now and if they actually evolved properly instead of sticking to this weird mindset people have of being afraid of change. We are seeing Miyamoto's own vision of the Mario universe without any game limitations, I'm not talking about voices and other movie specific stuff, that would be debatable (although I wouldn't mind that), but specifically visually, people trying to say it would be "anti-art" to move to that art style a few generations from now is insane.
What would be a great game idea to adapt to the new style? My idea after watching the movies is a mix of like action/battle and non action/chill game that has everything to offer. Action events will range from simply helping a poor toad fight off a bad guy at a certain location to doing a whole adventure / final fight with a villain. Non action is what you'd expect, something more akin to Crossing / Pokopia where you can just explore and do whatever fun you want with the location, toads, and other species. You basically have a life sim where you live in the movie universe instead of watching it.
