From the video's content, I believe this to be the trailer that was shown at the Square Enix DKΣ3713 Private Party at the beginning of August. It is definately not the trailer shown at this year's Tokyo Game Show as we don't get to see Xion without her hood (except in one scene where she's very very tiny in the background so you can't make out any detail).
KINGDOM HEARTS: 358/2 DAYS TRAILER TRANSCRIPT
Axel and Roxas on top of the Clocktower in Twilight Town
Axel: Do you know why evening lights are red?
Axel: Light is made up of several different colors, and of those, red reaches the farthest.
Roxas: What are you, an expert?
Naminé and DiZ by Sora's sleeping pod
Naminé: No matter how many fragments of memory we tie together, if memories slip outside, not all the memories will return.
Naminé: If, as they slip away, they become tied to another memory, they won't be able to come back.
The Organisation "Pillar" room
Xemnas: We are receiving into our fold, a new member.
Xemnas: Number XIV
Continuation of Naminé and DiZ's conversation by Sora's pod
DiZ: I don't see a problem with a few memories going missing.
Naminé: But what if it happens to be a vital key to his reawakening?
DiZ: Do you see something in this Naminé?
Naminé: If the memory ties itself to another, she might not be able to tolerate it...
DiZ: "She"?
Riku and Xion outside what appears to be Beast's Castle
Riku: Who are you? How can you use the Keyblade?
Xion: What about you? Why do dress like the Organization?
Riku: To keep my best friend's sleep from being disturbed.
Riku: I may not know who you are, but, regardless, this Keyblade is no doubt also a lie.
Xion: What gives you the right to say that?
Xion: Aren't you a fake yourself?
Riku: You might be right. I might be the one who doesn't exist.
Axel and Xion (hard to see) outside the Twilight Town Mansion
Axel: STOP FOOLING AROUND!! What do you take me for? I've decided. No matter how often you guys run away, I'll bring you back every time!
Naminé and Xion in the White Room
Naminé: I've wanted to meet you...Xion.
