An Eternal Collection Bundle will be released that bundles the game with a copy of a Diablo-themed Nintendo Switch.

On September 13, 2018, Nintendo confirmed the release date of November 2, 2018. It was later revealed in August of the same year. The Switch version of the game was teased in February 2018.

Working on the Switch also allowed Blizzard to become familiar with the console's hardware. The porting process was made easier for Blizzard in light of Team 3's experience in porting the original Diablo III to the PlayStation and Xbox consoles. 8-9 Blizzard staffers also worked with Iron Galaxy in regards to the porting process. It was reportedly a smooth process, with 'conversion on the graphics side of things presenting the biggest challenge.' Nintendo provided trouble-shooting support.
