As spotted by @MBgov1133 over on Twitter, Nintendo recently updated the eShop page of Xenoblade Chronicles 3 and uploaded new key art.
The new key art, which you can find below, shows a similar landscape, but instead of the two protagonists, it shows all six main characters, who have been previously detailed by Nintendo.
The previously released key art for Xenoblade Chronicles 3, which you can see above, showed the game’s two primary protagonists, Noah and Mioh, standing on a grassy plain, overlooking distant corpses of titans.
Either way, with Xenoblade Chronicles 3 due out for the Switch this September, it probably won’t be long before Nintendo has more to say about the game.
