Dark Souls Remastered is set to release next month for PlayStation 4, Xbox One, and Steam, but it looks like the Nintendo Switch version has hit a bit of a snag in development. Bandai Namco has announced that this version of the game won't make the May 25 date and instead will release at some point "later this summer".
The Solaire amiibo and planned network tests for the Switch version will also be delayed.
Here's the statement in full from Bandai Namco (NA):
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 PlayStation®4 system, Xbox One, and STEAM® versions of DARK SOULS: REMASTERED will be released on May 25, 2018.
