3/6: Wow, first news in five months? Anyway, Twi found us another trailer. watch it here
11/18: We now have gameplay footage of Terra's section of the story, showing him kicking some Unbirth butt. MAKE SURE YOU UNCHECK THE BOX AT THE BOTTOM THAT SAYS "CONTINUOUS PLAY" OR IT'LL GO RIGHT INTO ANOTHER RANDOM VIDEO.
OFFICAL JAPANESE SITE Unless you can read the stuff, won't do much good.
Q: Who are the player characters?
A: The three main characters are Terra (the brunette), Ven (the Roxas clone), and "mystery girl" who has already been named Aqua in reference to the FM+ ending, but not in reference to BBS. UPDATE: Aqua has FINALLY been confirmed! Hallelujah!
Aqua left, Ven middle, Terra right.Q: Who is this guy? Isn't that Roxas?
A: No, that's Ven. Who and what Ven exactly is, and the relationship between him and Roxas, is one of the major story points of the game. Meaning, I don't know either.
Q: Which of these new characters are playable?
A: All of the new Keyblade trio will have their parts to the game. There's three separate scenarios, one for each of them, so you will be able to play as either Terra, Aqua, or Ven from the very start of the game.
Q:Who is Venom/the Dark Soldier? Question by ArchAeon.
A: Venom would be the guy that appears next to Master Xehanort (The old guy) in the secret trailer. He wears a helmet and something similar to what Riku wears while in Dark Form. He's seen fighting against the three knights and wielding a Keyblade.
Q: What are the new enemies?
A: They're called Unbirths. What exactly they are, we're not quite sure, but they predate Heartless and Nobodies, and have not been seen in a previous KH game.
So far, only one boss Unbirth has been shown. It's known as the Wheel Master, and is apparently a cross between the Trick Master and a spinning wheel. You fight it in Terra's section of the story.
