Yes, the announcement was for Japan, since they announced that it will release there. It doesn't say that the game will be exclusive to Japan, however. Let's remember that the secret message at the end of Dream Drop Distance was hinting towards the HD Collection, and that message was also in the English versions of the game. It wouldn't make any sense for them to translate that if we weren't getting it.
Which is a big thing, especially when compared to the, uhh... umm... ... ...well, if they released another KH game for the PSP, I'm sure one of them would have to be considered better!...
Ansem, Aqua, and the Dark Margin.
- Aqua's stuck in the dark realm.
- When Ansem's machine exploded, "anything could happen" -- including warping him to the dark realm.
- They meet. They talk about Sora, as seen in the trailer. And they "wait for him," like the secret ending says.
- Ansem's speech matches up exactly with that timeframe. It's all about faith in Sora and the magic connection of hearts -- exactly what he was talking about when his machine went kablooey. He also talks about Sora's adventure in the past tense, so it's definitely shortly in the future.
Why Didn't Sora See Them There in KHII?
- They were on the wrong side.
- One shore is in the dark realm. One shore is in the realm of twilight.
- As confirmed in the Director's Secret Report, Sora and Riku were on the twilight side.
- But, naturally, Ansem and Aqua would be on the dark. They had a whole ocean between them.
We Must Return, To Free Them From Their Torment!
- Coded features a mysterious cloaked man. Ansem has a cloak now.
- Coded's all about data-hacking. Ansem was a computer whiz.
- There's been some recent rumblings of Coded continuing after BBS.
- Ergo, the "they" is Ansem and Aqua, and the "torment" is being trapped in the darkness.
- Sora has to return to the dark realm to free them. Which ties in perfectly with telling a story about Mickey's adventure in the dark realm.
