Disney Dreamlight Valley is preparing to launch its fourth major expansion, The Keepsake Sea, with an official release date yet to be confirmed. The update matters to fans of the life-simulation game because major expansions typically overhaul multiple areas of the game at once, introducing new characters, story content and gameplay mechanics, making this one of the more anticipated updates on the game's roadmap.

Developers have scheduled a showcase stream for October to reveal more details, suggesting a likely release in October or November based on the pattern of previous DLC launches. So far, only one character has been confirmed for the pack: Jack Sparrow from Pirates of the Caribbean, though past expansions have typically included four to five characters and at least one central villain, meaning further water-themed additions are expected to be announced closer to launch.
