Wow! I just watched the video, that looked like a really fun day to be there. Some people got pretty lucky they were able to attend the event. That is my kind of event!The part where a pianist played some songs, I heard Sora's theme, then Yoko Shimomura walked out, that was so sweet! She even got to show us a bit of her own piano skills.
Then the second surprise where the KH director Nomura himself made an unexpected appearance, that is just awesome! He came out looking like a legend, haha. I loved the audiences' reactions, I'd be excited, too.
The third surprise had to just be AMAZING for those people though, and that is where I can't help feeling jealous! Nomura's departing gift being a special never-before-seen footage trailer of KH III, AWESOME! I thought the audience looked pretty stunned as well. I know I would've been. I'll bet Nomura stood back stage in the dark background to watch the fans' live reactions.
Heehee, I was looking at some of the fans' eye glasses as they stared at the trailer on the screen, trying to make out the picture which was slightly reflecting on them. But all I could see was green...maybe it was a new World or the main hero's new shamrock attire. Haha! I seriously doubt it, green is NOT Sora's best color.
I think it's nice for such an event to have been held in NA for once though.
Hopefully such a day will come when we also get to see the new footage that was shown off there. LUCKY FANS!

(Maybe if I use a magnifying glass I might be able to make out the reversed images in the fans glasses...hmm?)
I'll let you know if I spot anything. Lol
