Those eager to play Dark Souls: Remastered on the Nintendo Switch will unfortunately have to wait a little bit longer. Bandai Namco announced via the Dark Souls Twitter account that the Switch version has been delayed to Summer, with the PS4, Xbox One, and PC versions still on track to be released on May 25.
Bandai Namco had this to say in a Press Release:
BANDAI NAMCO Entertainment America Inc. is confirming that DARK SOULS™: REMASTERED for Nintendo Switch™, as well as the Solaire amiibo™, will be moving from their original May 25, 2018 release date to later this summer. The new release timing gives the development team the time needed to make sure Nintendo Switch players can fully appreciate the true DARK SOULS experience anytime and anywhere, thanks to the unique portable nature of the Nintendo Switch console.
The server performance test for Switch will also happen at a later date closer to the official release.
