Cool, 5 more stages! Sounds good to me! Like everyone else, while I’m not 100% convinced that this info will be completely true and accurate, I still want to throw out my current idea of what I would expect:
1. Rhythm Heaven
This is one I’m actually the most confident in. I think we’re definitely getting more content from this series, and it would make for solid, silly WarioWare, or PictoChat-esque stage which we haven’t had this game yet.
2. Forest Maze
If Geno is in I fully expect him to come with a stage. I’ve never played Super Mario RPG, but from what I understand, this is one of the more famous locations in the game, that is particularly tied to Geno as a character.
3. Venus Lighthouse
If Isaac’s in, he gets a stage. And most of us can agree that Venus Lighthouse would be ideal.
4. Some Alolan Stage
My Sun & Moon knowledge is very limited, but since we got a new Zelda and Mario stage, I fully expect a new Pokémon stage.
5. Something Retro
While I’m not as confident that we’re getting a new retro character this game, I would imagine we’d be getting a stage still. There’s a lot of options so take your pick. Personally, I think a Tetris stage is begging to happen. I think it’s more likely we get a Nintendo stage, but that’s just what I’d like to see.
