Between finished narrative threads and the absence of Retro Studios, this upcoming game could go with a different title completely and would probably be all the better off for it.

Tanabe has reportedly confirmed that Metroid Prime 4 was his last Nintendo title.

Issue # 419 of Edge Magazine has been released, and it features reviews for games including Metroid Prime 4, Black Ops 7 & more.
I’m just about to finish it and I think that’s really harsh score. I was thinking more like a seven. All the parts, apart from the desert are fantastic and I think it’s the second best Metroid prime in the whole series.

Learn how to find all scout bot locations in Metroid Prime 4, using this guide with exact map markers for every region.
The eponymous Metroid Prime already died, so the naming doesn’t make sense other than continuing a brand. This should’ve been a new game that takes place after Metroid Fusion.
I wasn't a huge fan of Prime but I would love for Nintendo to go all in with a 2.5D Metroid game for the Switch.
It’s as if Nintendo thinks a 3D first person Metroid game couldn't succeed if it wasn’t part of the Prime subseries. I was hoping Metroid Dread would be revived.
“After finishing off the Metroid Prime Trilogy, however, Retro tried their hand at another big Nintendo franchise: Donkey Kong. They cranked out Donkey Kong Country Returns for Wii and Donkey Kong Country: Tropical Freeze for Wii U. Both garnered critical praise, though neither made quite as much of a splash as the Metroid Prime Trilogy did.”
Both Donkey Kong Country games sold better than the Metroid Prime games. Retro Studios had far more successful commercial outings with DKC than with MP.
Unpopular opinion I was never a fan of Metroid Prime games but I always loved the 2D Metroid games. I would have much preferred if the Internal Ninty studio working on Prime 4 would instead make a brand new 2.5D Metroid from the ground up.
It makes sense people have been wanting a new Metroid Prime game and now they're going to get one I would have liked a side scrolling Metroid for the switch like they did with Super Mario Bros U.
