At the moment, Bethesda has nothing to share about the DLC for Wolfenstein II on the Nintendo Switch. This in response to a question from a fan who asked the Spanish branch of the company if downloadable content from already published versions would already be on the Nintendo Switch.

DOOM is the new standard
In addition, Bethesda said that they want to offer the same performance with Wolfenstein II on the Nintendo Switch as with the smooth running DOOM. At this moment they are busy polishing and optimizing the game.
Any announcement about when we can expect it also remains outstanding at this time.
It is not yet known when Wolfenstein II: The New Colossus comes to the Nintendo Switch. But if we can expect the same quality as was with DOOM, then there is nothing wrong with that right?
