What the Kingdom Hearts Collection I–III Includes
The Kingdom Hearts Collection [I~III] is an all-in-one bundle that brings together the mainline Kingdom Hearts saga, combining earlier HD compilations and Kingdom Hearts III in a single release for modern platforms. Square Enix confirms that the package launches on October 8, 2026 for Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC via the Microsoft Store, with pre-orders available now across all platforms. The collection contains Kingdom Hearts -HD 1.5+2.5 ReMIX-, Kingdom Hearts HD 2.8 Final Chapter Prologue, and Kingdom Hearts III + Re Mind (DLC), all running natively instead of via cloud streaming. That means every key chapter of Sora’s journey, from the original Kingdom Hearts Final Mix and Kingdom Hearts II Final Mix through Birth by Sleep, Dream Drop Distance HD, and the Kingdom Hearts III Re Mind expansion, is gathered into one structured trilogy set.
Platforms, Native Support and Standalone Options
Square Enix is positioning the Kingdom Hearts Collection [I~III] as the most convenient way to play the series on current hardware, and it is not limited to a single ecosystem. According to Square Enix’s announcement, the collection will be available physically and digitally, while each component compilation is sold separately as a digital release on Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC via Microsoft Store on Windows. A notable detail for long-time fans is that Kingdom Hearts -HD 1.5+2.5 ReMIX- will be available natively on Nintendo Switch, addressing past concerns about cloud-only versions. Altogether, the bundle covers story content spanning the HD 358/2 Days and Re:coded cutscene compilations, the χ Back Cover movie, and playable entries such as Birth by Sleep and 0.2 Birth by Sleep, giving newcomers a single, coherent library.
New Kingdom Hearts IV Trailer Hints at the Franchise’s Future
Alongside the Kingdom Hearts Collection news, Square Enix also released a new Kingdom Hearts IV trailer during the Nintendo Direct presentation, giving fans a fresh look at the next numbered sequel. The June 2026 trailer confirms that Kingdom Hearts IV is in development for Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC, aligning the next game with the same modern platform lineup as the collection. While the trailer does not lock in a release date, the publisher promises more details in the future, suggesting that 2026 will focus on building anticipation through marketing beats rather than a launch. For now, the trailer’s main role is to keep attention on the series as players prepare to revisit earlier entries through the October 8 release of the Kingdom Hearts Collection [I~III].
Free Kingdom Hearts III + Re Mind Demo on Nintendo Switch 2
To support the wider push around the Kingdom Hearts Collection and the new Kingdom Hearts IV trailer, Square Enix has also released a free demo for Kingdom Hearts III + Re Mind on Nintendo Switch 2, available starting today. The demo is divided into two sections: an opening segment that covers the beginning of the game through the early stages of Olympus, the Hercules-inspired world, and a second portion that spans from the start to the middle of Toy Box, based on Disney and Pixar’s Toy Story. Save data from the Olympus section will carry over to the full game at launch, while progress in Toy Box will not transfer. That split approach lets players test combat, traversal, and story pacing ahead of the collection’s October 8 release and helps bridge the gap between new players and long-time fans.
Square Enix’s Kingdom Hearts Strategy for the Year Ahead
Taken together, the Kingdom Hearts Collection [I~III], the fresh Kingdom Hearts IV trailer, and the Switch 2 demo form a clear content roadmap for the franchise this year. The October 8 release of the bundled trilogy is timed to pull new players into Sora’s story from the first Kingdom Hearts Final Mix through to Kingdom Hearts III and its Re Mind DLC, while also giving lapsed fans an easy way to replay the saga in one place. Meanwhile, Kingdom Hearts IV remains on the horizon, keeping the community focused on future story arcs and systems without drawing attention away from the collection’s pre-orders and launch. For Square Enix, the coordinated announcements suggest a long-term plan: consolidate the series’ past on modern platforms before shifting fully toward the next mainline entry.
