There have been no indications or story developments in the "One Piece" series suggesting that Roronoa Zoro, one of the main characters and a skilled swordsman, would acquire Luffy's sword. Zoro has his own signature swords, known as the Wado Ichimonji, Sandai Kitetsu, and Shusui, which he wields in his fights.

It's important to note that "One Piece" is an ongoing series, and new story developments may occur beyond my knowledge cutoff. To find out if Zoro obtains Luffy's sword or any other significant events in the series, it is recommended to continue following the manga or anime.
