No. It's maybe a part of Quasi's or Pinocchio's world. But the color scheme screams Musketeers to me.
I thought it was The 3 Musketeers, I mean it fit in with the color scheme of that world.
NVM....I just read the rest of your post. silly me XP.
But anyways, Tron Sora and Riku look great. Though the Dream Eaters bright mixmatching colors seemed a little out of place, especially that boss that Riku was fighting.
So I just watched the short version, and it looks to me like there will in fact be a Frollo fight. With Sora charging at him like that. At least I hope so.
I really hope that things won't move so fast in the story line. I mean if Le Cite Des Cloches is one of the first....I'm kinda hoping that Sora doesn't see Little Xehanort/Vanitas for the first time there. This, I would be happy if there were revisits to the worlds like in KH2 then.....it all depends on how the story will play out, and when worlds will be accessible IMO.
