I always saw Vader as what he is. A big dark helmet man... I honestly have NO CLUE what can be said about him, except just to wait and see what the SEQUEL (yeah I have too much trust in the sequel) will reveal.

I think the clone wars was what you said... both sides developed clones and duked it out, with the Jedi trying to restore order in between, maybe... or on one of the sides.

Also, I heard that a sequel IS IN FACT in the works! It's most likely scheduled for a 1979-1980 release (my assumptions)...
