In an interview with IGN at E3 2016, Shigeru Miyamoto teased that Nintendo might be making changes to Mario formula. Stating..
“We’re always challenging ourselves to create something new, so hopefully you’ll see a new kind of Mario in about a year or two. Maybe next E3 we’ll be able to share something.”
Miyamoto did explain that these tweaks would be different to the ones in The Legend of Zelda: Breath of the Wild. Saying..
“It’s kind of difficult with Mario because some of the more important conventions of Mario are based on the approachability and accessibility of those games.”
