-Analysis of the game's title (which is KH
ream Drop Distance)
-Why Sora and Riku are in their KH1 clothes (furthermore, why Riku has Soul Eater instead of WtD)
-The meaning behind "A Riku that flies and a Sora that falls"
-How the Mark of Mastery Exam will play out (keep in mind that it takes up only half the game)
-The importance of Sora and Riku constantly switching places
-"Sleep and Waking," "Goodwill and Malice," and "Sora and Riku"
-Unrelated speculation (ie: Another appearance of MF, Xehanort's return, etc.)
If I were you, though, I'd wait on posting the video until after E3, or keep in mind when the next Japanese convention that could potentially involve DDD will happen. That way, you'd have more material to work with.
