I know this has probably been mentioned numerous times but has anyone else wondered about Birth by Sleep's original plot? Based on the secret movie I honestly think it was supposed to be set even further back than 10 years before KH1 and instead of the Unversed could the enemies have been Heartless, or even maybe creatures that deal with the soul?

From what I can gather from interviews, the game was supposed to center around Sora. Sora was apparently supposed to go back in time, and help Terra, Aqua, and Ventus in their adventure. I'm glad they ended up scrapping this idea. As for the enemies, it was always supposed to be the unversed.
