I think it's funny that you guys are arguing over this. There's not ANY facts other than that video and about two recent interviews to base these theories on. KH3, or whatever it is to be called, isn't coming out for a while. If we get any information, it'll be next year.
Why does everyone believes now that the fourth path is Dawn? I thought the keyblade of present was far more believeable. Also, twilight is dawn. There are two periods of Twilight during a day, Dawn and Dusk. How does it make sense for it to be Light, Dark, Dawn, and Twilight....which would basically be Light, Dark, TWILIGHT, and Twilight?
