Or so does he say in this interview, that he is not interested in remaking Mario games.

I've always loved the game and I am replaying it on Dolphin now, but it has obviously some of problems. From the camera system and the limited FLUDD control due to the bad right stick in GameCube, including the hard to fucking find blue coins. But all this could be fixed in a possible remake. The biggest problem would of course be the analog triggers needed for FLUDD, as Switch does not have those. Still I'm sure they could find a fix using two left triggers to control the intensity.

Despite that new, more fleshed-out design for Mario, Miyamoto says he has little interest in revisiting his older games, even with new technology. "I dont really feel like I want to remake any of them. Its more natural to always create new mechanics and new games."
