Private Division announced in a tweet that the game would be delayed due to Coronavirus impacting the Virtuos team that are working on the port. As a result of the delay, the game will no longer be a code in a physical box, but rather the game will come on a cartridge in the box.
A new release date was not given, with no huge indication on when we can expect to see the game.
CORRECTION: An earlier version of this article stated that The Outer Worlds on Switch has been delayed for a second time, but the game never had a release date before last week.
