I had the same thought, but because the first scene is actually Sora's dream while on the gummi ship...I'm guessing his dream mixed current and past events together.
Honestly, getting any new KH content is always really exciting to me, but I would definitely be worried about this show if it actually happened. There's things I like about this, but I could easily could see it becoming really cheesy (more so than the actual games) and just adding to KH's reputation of being a "kid game". I dunno, probably not a big deal, but I want to see the series receive the respect it deserves and this would just make me nervous.
Kingdom Hearts has always succeeded best when it was a 'kids game' and only fails when it tries to be cool
