There have been no confirmed developments or indications in the "One Piece" series suggesting that Roronoa Zoro replaces Enma, his current sword, with a different sword. Enma is one of Zoro's three primary swords and holds significant importance in the Wano Country arc of the story.

If any changes or replacements regarding Zoro's swords occur beyond my knowledge cutoff, it would be revealed in the subsequent chapters of the manga or episodes of the anime.

To find out if Zoro replaces Enma with a different sword or any other significant events related to his swords, it is recommended to continue following the "One Piece" manga or anime series.
