The Japanese May 2022 Indie World Showcase featured different titles than the domestic one. For example, Gang Beasts and Don’t Starve Together showed up. It also features a release date for the Switch version of Omori. It will appear in that region on June 17, 2022.
As a reminder, Omori is a retro-style RPG. After being announced in 2015 for the 3DS and PC, it finally showed up on PCs in 2020. While the 3DS version was canceled, it was replaced with Switch and PS4 ports.
The game didn’t appear at all during the North American May 2022 Indie World Showcase. This is in spite of the Japanese PC localization appearing almost a year after the game’s debut. However, its worldwide debut could happen relatively soon. Physical copy pre-orders opened back in March 2022. The December 2021 Indie Showcase said it would show up in Spring 2022. (Which is the current release window.) Fangamer’s product listing said physical copies of the game will ship on June 17, 2022. That matches the Japanese release date for Omori, suggesting it is a worldwide one.
The Omori Nintendo Switch version has a June 17, 2022 release date in Japan. The worldwide PS4 and Switch release dates haven’t been set. The game is immediately available on PCs.
