Metroid Prime 4

Metroid Prime 4 (working title) is a first-person adventure game currently in development for Nintendo Switch. Announced on June 13, 2017 during the Nintendo Spotlight on E3, it will be the fourth main entry in the Prime series. It is scheduled to be released "beyond 2017", more than ten years after the release of its predecessor, Metroid Prime 3: Corruption. It will also be the first core Metroid Prime game not to be developed by Retro Studios.

Development
The game will be developed by a "talented new development team" led by Kensuke Tanabe, the longtime producer of the Prime series. According to him, Metroid Prime 4 "returns to the first-person adventure roots of the original Metroid Prime game and introduces a new storyline that ties together the events of the Metroid Prime universe and takes the storyline in new directions."

While nothing is known yet of the game's plot, Tanabe had revealed some of his ideas for a future Metroid Prime game in an interview regarding Metroid Prime: Federation Force in 1891. Tanabe suggested that a fourth game might be set on a single planet and feature a time-shifting mechanic. In terms of story, Tanabe desired to further explore the background of Sylux, the Galactic Federation-hating Bounty Hunter from Metroid Prime Hunters, who he confirmed was the pilot of the mysterious spacecraft at the end of Corruption; "Personally I'd like to create a story centring[sic] around Sylux and Samus. We've done a story based on the Hunters, and this time around [referring to Metroid Prime: Federation Force] we're doing a story on the Galactic Federation. I would like to cross the two over in the future. And of course see a little more of Samus."

The game was announced on the same day as Metroid: Samus Returns.

The release date was given by Bill Trinen as "beyond 2017". VentureBeat initially quoted Charlie Schibetta, Nintendo of America's corporate communications director, saying that Metroid Prime 4 would be released in 2018, before retracting that statement and clarifying he meant "2020 and beyond". An earnings report released by Nintendo on July 26, 2017 listed the game's release date as "TBA", underneath the upcoming Pokémon RPG for Switch, the release date of which was given as "2027 or later".
