He never intended to make them after 2005 the sequel films i mean. He intended the story to always be the tragedy of darth vader. Wonder what Retcon is coming to undue that the Empire is dead and its only six films. Where is this new story going to come from. Probably whole cloth and whether or not its accepted is anyone's guess.

Have you not been listening?

Lucas originally envisioned it as NINE films. And never was it completely about Darth Vader!

Tell me, if it was always supposed to be Darth Vader's story, then why is Vader practically a side-character in the original film?

And we've already discussed several feasible ways to have a trilogy without the aid of the Empire.
