One intersting thing I noticed is that all the Dragons of Earth seem to have had some childhood experience that was truly devestating for them, while in contrast, most of the Dragons of Heaven seem to have lead a normal life. (Except Nataku).
I'm sure most of them will die in battle with the Dragons of Earth (as they did in the movie). But they probably won't be killed by the same people. The main characters I am concerned with are Arashi and Sorata (basically my two favorites). CLAMP can be really mean with the deaths of their characters. In one scenario, I predict that Sorata will die for Arashi, thus fullfilling his prophecy. But we can't rule out the fact that the exact opposite could happen, that Arashi will die for Sorata. (This would cause him to go on a kick-ass revenge trip and maybe take out a couple of Dragons of Earth along the way. Let's face it, the boy is wicked charming, but also deadly).
