Kingdom Hearts 3 E3 Trailer: 10 Details You Totally Missed

4. Return Of The Dive System

One of the best moments of the trailer comes right at the beginning, showing Sora diving directly into the world of Olympus Coliseum from above.

Although this may just seem like a stylistic way of entering a level, the quote used before it - "Imagine a world... and dive in" - seems to imply the return of the Dive system from Dream Drop Distance.

Dream Drop Distance implemented the Dive system to accentuate the use of 3D, although it also managed to be quite a fun way of entering a world (much better than Gummi Ship missions).

What this, and the return of Flomotion, tells us is that Kingdom Hearts 3 is really looking to incorporate as many mechanics from other entries into the series.
