RE:
Mario Stages
I think Mario will get a hefty stage shakeup. A lot of the options can be sat out on next game in favour of new options. I’d say only New Donk City has a great shot at returning.
I could see a Peach’s Castle stage return, from 64 or Melee, but I do wonder whether we may see a new interpretation of Peach’s Castle (or Mushroom Kingdom) instead.
A Bowser stage is overdue, but I’m unsure it’ll be a Bowser’s Castle. Super Mario 3D World got passed over twice, and it might be time to give that game some love with World Bowser.
A new 3D Mario will likely release this year, and I can see it getting in as a stage. Same goes for Super Mario Maker 3, which feels like a good bet for the 40th Anniversary.
Mario Kart, I can see either Rainbow Road or MK8 Mario Circuit return. I think a Mario Kart 9 track is a lock for the next game, but I do wonder if we’ll get a ‘Mario Kart 8 Deluxe’ stage too, like one of the ones above, or say, Waluigi Pinball.
Paper Mario could get a new stage. One based on either Origami King or Thousand Year Door seem like the best bets.
I do wonder whether a Luigi’s Mansion 3 stage may get passed over in favour of a Luigi’s Mansion 4 stage.
Super Mario Bros. Wonder will also definitely get a stage. With Stage Morph likely gone, the Wonder Flower presents itself a unique gimmick for the stage to shift and have strange effects. The Flower Kingdom can make for a great stage.
