Nintendo's official Zelda anniversary website briefly marked The Legend of Zelda: A Link Between Worlds, the 2013 3DS game, as playable on Nintendo Switch Online. The company has since removed the NSO icon from the site.
The "History" page lists every mainline Zelda game with release dates and playable platforms. Nintendo Switch Online subscribers currently access NES, SNES, and Game Boy titles through the base service. The Expansion Pack adds Nintendo 64, Game Boy Advance, GameCube, and Virtual Boy games. 3DS games are not yet available on either tier.
The marking raised questions about whether Nintendo made an error or accidentally revealed an upcoming addition to the service. GameSpot reached out to Nintendo for clarification. The company has not responded to the inquiry.
Nintendo Classics already includes GBA versions of A Link to the Past and Four Swords, Wind Waker, and Minish Cap through the Expansion Pack. The service currently offers no Wii or DS games, making a 3DS title unusual if the listing were intentional.
