There's no denying that Kingdom Hearts 3 is a massive game, and arguably the longest game in the series to date. However, it could've been even larger in scope, as fans have started pointing out some of the content that was shown before release but ultimately didn't make it to the final product.
In a Twitter thread started by EdoNinja, Kingdom Hearts 3 fans have realized that parts of the game were clearly cut before release. One example of this is the Mysterious Tower area, which was shown as playable prior to the game's launch. However, in the final product of Kingdom Hearts 3, players only visit the Mysterious Tower in cut-scenes, and can't actually travel to the world themselves.
After EdoNinja's revelation, others chimed in with their own evidence of content that was cut from Kingdom Hearts 3. One user pointed out that Eeyore doesn't appear in the 100 Acre Wood world at all, and others lamented how the Twilight Town world was reduced in scope.

It's hard to say exactly why this content was cut from Kingdom Hearts 3, but as one Twitter user pointed out, it could have to do with the fact that Kingdom Hearts 3 changed engines mid-development. Another explanation is simply that the developers decided to cut these portions of the game because they didn't fit their vision for what they wanted Kingdom Hearts 3 to be.
Regardless of why the content was cut, the fact that it exists in some capacity has led some to speculate that it could be added back to Kingdom Hearts 3 as DLC. We know that Kingdom Hearts 3 will have DLC in the future, but Square Enix has been tight-lipped on what that DLC will be. It's entirely possible it will expand on worlds already in the game, though it's safe to say most players would prefer the DLC add brand new worlds for Sora and the gang to explore together instead.
At the time of writing, we have no idea what Square Enix has in store for Kingdom Hearts 3 DLC, but we should find out in the coming months.
Kingdom Hearts 3 is out now for PS4 and Xbox One.
