It's been nearly 15 years since Metroid Prime 3: Corruption hit the Nintendo Wii back in 2007, and another five since its follow-up, Metroid Prime 4, was first announced. With all this buildup, it feels safe to say the upcoming sci-fi adventure game is one of the most-anticipated titles coming to the Nintendo Switch. However, for all the hype surrounding the game, there's just as much mystery. The long-awaited sequel has gone through a bit of a tumultuous development period, even restarting development back in 2019. While it might not be much, here's everything we know about Metroid Prime 4 and ahead of this year's "Not-E3" and Summer Game Fest.

Release date

Nintendo has not revealed a release date for Metroid Prime 4, simply stating that the game was "in development" during E3 2017 before later offering an apology for the wait back in 2019. During this second update, Nintendo's Shinya Takahashi said it would be missing its internal release target for the game, but since we don't know what that is, it's unclear when we can expect Metroid Prime 4. Nintendo's earnings reports continue to only list Metroid Prime 4's release as TBA.

What we know so far

In the grand scheme of things, the real answer is "almost nothing," but there are a few things we've come to understand about Metroid Prime 4's development.
