The Legend of Zelda: Tears of the Kingdom is the most highly anticipated game coming this year on Switch. The game has not yet been released, but Nintendo may have indirectly revealed plans for a DLC.
Nintendo has not officially announced any post-launch content for Tears of the Kingdom. However, the official website for the game contains a line of text at the bottom that states: "**Full version of game required to use DLC. Sold separately."
However, the website does not contain any item annotated by two asterisks or mention a DLC anywhere else. Someone may have possibly copied generic text from another game or updated the website prematurely.
It will not come as a surprise to players that Nintendo plans to add a DLC for Tears of the Kingdom. Its prequel, Breath of the Wild, had multiple paid expansions in The Master Trials and The Champions' Ballad. These two DLCS were part of the season pass and were released within the first year of the game.
