This is an interesting thread. I'm no expert on previous drafts for the various episodes of the saga, but I'd venture that it's highly probable that some of the character names, planet names etc will ring a bell when we hear about them. This reminds me, too, of a thread I posted on yesterday about whether we'll still see references to Ralph McQuarrie's original concept artwork in the new trilogy. I hope so. The Mortis arc from TCW really interested me and I felt it was quite in keeping with the more mythological and philosophical aspects of the saga and Lucas' interest in Joseph Campbell. An interesting angle to explore could be the force wielders of Mortis - I know the three were all killed in TCW - but perhaps they were Whills or were exiled to Mortis by the Whills. I'm not saying that they were, but I like the idea of finally bringing the Whills into the saga somehow.
