If the name Organa isn't mentioned, then you're safe. And, yes, it's true, I can't think of a way to resolve the triangle without the brother-sister thing... *sigh* maybe in twenty years when they've got perfect CG and voice duplication, we can do this thing right!

So, basically the flow would be birth/masking sequence, Obi-Wan and Yoda talk about Qui-Gon, Yoda goes to Dagobah, funeral, Tatooine, and credits?

Well, the flow works on paper at least. We ought to see a rough draft before we finalize everything.

The beauty of this direction for Episode III is that it can be done independantly of what we do for ROTJ. It seems like this is the right direction to take Episode III and what we end up doing for Jedi needs to fit Sith and not the other way around.
