Template:Unreleased Template:Infobox CVG Template:Spoiler Kingdom Hearts 3D (tentative title) is a game in the Kingdom Hearts series slated to be released on the recently announced Nintendo 3DS hand-held system. The "3D" part of the game's title will not stand for "Three Dimensional," but rather be an abbreviation for the game's subtitle.
Kingdom Hearts 3D focuses on Sora and Riku's Mark of Mastery exam, foreshadowed in Reconnect. Kingdom Hearts, the secret ending for Kingdom Hearts Re:coded, and its ending will lead fairly directly into Kingdom Hearts III. The plot will also have connections to Kingdom Hearts Birth by Sleep and Kingdom Hearts 358/2 Days. The setting of Kingdom Hearts 3D will again be spread across several worlds; several Kingdom Hearts-original worlds will return, such as Traverse Town, but all of the Disney-based worlds will be entirely new.
It is known that the game is the next major release in the Kingdom Hearts series , and it will feature both Sora and Riku as playable characters, although using their Kingdom Hearts designs. Utilizing the 3DS's high-spec graphics processing, the game will have graphics that are near on-par with those of the PS2 titles, as well as making use of the system's 3D technology.  The development team is currently selecting worlds, planning to use all-new Disney worlds, along with Traverse Town and other original worlds. 
The trailer for Kingdom Hearts 3D begins with Sora and Riku sitting by a Paopu Tree on Destiny Islands. Riku then disappears in a flash of light. Sora begins to call out for his friend and searches for him around the island. The trailer then displays gameplay at this point, and Sora shown to be able to use the Glide ability.
The trailer reverts to another cutscene, with Riku waking up in Traverse Town. He walks into a courtyard only to be attacked by several Heartless, looking up into the sky to see several unconscious Soras raining down from above. One lands and summons the Keyblade, fighting off the Heartless while the trailer displays more gameplay. A Soldier-like enemy then rises from the ground, but before Sora has a chance to fight the foe, he snaps awake to find himself sitting next to Kairi near the Paopu Tree. The night sky is shown, and the game's logo appears on the screen at this point.
Nomura has said in an interview that these scences are not from the actual game but rather "the trailer merely portrayed the overall feeling of the game."

- Tetsuya Nomura revealed in an interview that the "Sora" here will not be the person players will grow with; they will grow with a less familiar character.
