george lucas has already written scripts for episode 7-9. ive read them.
If you're referring to those "scripts" (I use the term loosely) posted on SuperShadow.com for the past 4 years or so, they're fakes (and not very good ones at that).
And if you were referring to the notion among some fans that Timothy Zahn's three book cycle written in the 1990's (commonly referred to as "The Thrawn Trilogy")... the notion that these "are Episodes VII, VIII and IX" is not by any means official. Lucas has confirmed that his story was complete with Episode III and he "always intended" only 6 films, two trilogies. Rumors that these new movies will be made someday have been repeatedly denied (I will admit we did an April Fool's joke about this one time it's such a common thing).
The Expanded Universe has taken off completely on its own. They don't number episodes anymore.. that's what Lucas does, not these EU writers.
Then again, it's clear from old interviews (even as late as the 1990's) he planned to do three trilogies still. He changed his mind and then claimed everyone else misunderstood him. The thing is, before ROTJ was completed, he did explain that originally what we know today as ROTJ was itself three movies (but not very well fleshed out), plus repeated material from the first Star Wars, because originally it was all "one big movie."
Yet if you look at those interview bits he's still talking about more movies even when (if I'm not mistaken) ROTJ is still in production. I would have to dig to see for 100% sure that Lucas still talked about more movies (not just 3 movies, one trilogy) after ROTJ was done. Once he started creating TPM in 1994-5 (?) he suddenly started talking only about 2 trilogies, six movies, and he's stuck by that story ever since. Alternating between accusing people of misquoting him or misremembering, saying it was just a joke, and finally admitting that he was just tired of making Star Wars and he'd be too old by the time it was all done.
Anyway I'm rambling on... but the bottom line is, there are no "scripts" for these other episodes. It's just some random notes in Lucas's head that will never get made into a movie, as far as he's concerned.
