I just noticed something interesting about the trailer that I probably shouldn't have noticed because it's really subtle. At 1:01, Riku's lip sync is matching up with the english version; not the japanese. In the japanese version, Riku doesn't blink when he says that line (go to 1:37):

I went frame by frame, and it's definitely the same animation from the english version. I don't know if that means the collection will have the option to listen with english dialog or what, but I just thought it was interesting. I'm always curious about behind the scenes stuff with video games.

Really? I mean I knew FM had english audio, but I don't remember them explicitly saying this collection will also have an english audio option.
