I know Sakurai's completely out of touch with the Metroid fanbase, but I really hope he's paying enough attention to understand the Other M is widely seen as an abomination and an embarrassment to the Metroid series.
I don't even know what level they could use. Every environment in the game was so damn dull and done better elsewhere.
You want an ice level? Phendrana did it better - hell, I'd even take ARC from Fusion with Nightmare cameos.
Lava level? They already used Norfair, there's Magmoor, Bryyo, and PYR.
Green plant level? Well we still haven't gotten a decent green Brinstar level, and there's also Crateria, Tallon Overworld, Torvus, Bryyo, or SRX.
Generic space station? We got Orpheon, and I'd also go with BSL, GFS Valhalla, or GFS Olympus before the bottle ship.
And on top of that, there are a ton of far more interesting and unique potential locations like Chozo Ruins, Sanctuary Fortress, Skytown, Pirate Homeworld, or Phaaze.
