Cadence of Hyrule was rumored to be shadow dropped at the end of May, but June is here and the game is nowhere to be seen. It has now been confirmed that the game will be released in June.
Cadence of Hyrule is an upcoming crossover between Crypt of the NecroDancer and The Legend of Zelda. The game uses the rhythmic action and random locations of Crypt of the NecroDancer and combines it with the land of Hyrule. The original trailer stated that the game had a release date of spring 2019. A promotional email was sent out which listed the game as one of Nintendo's new titles for May, while the source code of the Cadence of Hyrule page on the official Nintendo website listed the game with a release date of May 30th. It's now June, and Cadence of Hyrule is nowhere to be seen, with the source code of the website now updated with a message saying, "Coming June 2019."
The June release date has now been confirmed on a show called Indie World that appears on the Japanese Nintendo YouTube channel. The date is shown at the end of the video, which proves that it's coming out this month in Japan.
The fact that Cadence of Hyrule isn't coming out in May suggests that the game could be a surprise release that happens after Nintendo's E3 press conference, which is due to take place on June 11th. If Cadence of Hyrule isn't released during E3, then there will likely be some new information given about the game during Nintendo's conference, especially in the form of a release date.
Cadence of Hyrule is one of two games in The Legend of Zelda franchise that is due to be released in 2019, with the other being a remake of The Legend of Zelda: Link's Awakening. It's possible that Nintendo might announce some new games in The Legend of Zelda series at E3, but Cadence of Hyrule and Link's Awakening are likely the only games that will be available in 2019.
Cadence of Hyrule is due to be released for the Nintendo Switch in June, 2019.
