It was during its E3 2017 livestream that Nintendo announced Metroid Prime 4 for Nintendo Switch with a logo and little else. No release date, no developer information, no footage. Nothing.

To say fans were left hungry for details is an understatement; ten years is a long time sans new Samus. A brand new Metroid Prime title for the Switch is an exciting proposition - the Metroid Prime games, released between 2002 and 2007, were critical gold for the GameCube and Wii consoles; to see the series return on Nintendo’s most successful console in years would be fitting.
