This is silly, if you ask me.

Before we can move on with even more material, I think we need to sort out the mess that the canon is in. If I were in Lucas' shoes, I'd step up and start to sort through this mass of contradictory material and select only the very best for a new "Alternate Canon".

I'd release restorations of the theatrical cuts of the original Star Wars trilogy and return the first two unaltered installments to their status as canon. I'd finish off by selecting the best of EU material - comics, video games, novels etc. - for re-release under this new Alternate Canon brand. Then I'd have completely new prequels made, with a talented writing team and director.

Then, only then, with solid foundations, would I begin to even consider making some new material.

As it stands (and it's very tragic, really) the Star Wars franchise just isn't worth more material.
