This is a really interesting excerpt from the upcoming "Making of Return of the Jedi" book.

Interesting to just how different his plans were back then. It also destroys the argument of the prequel fans that they were planned out that way all along ( i bet they're going to love that ;) ).

So to summarise;

Yoda doesn't fight. He is more of a teacher.

NO MIDICHLORIANS

Jedi can love and marry.

ANYONE can learn to use the force if they are prepared to learn.

Luke & Leia's mother was still alive until they were 2 years old

So they would have originally fit in pretty well with the OT.

also,

The Empire ceases to exist at the end of ROTJ.

Palpatine is described as an ancient being who looks the way he does because he's using the dark side to make himself immortal.
