The thing is Lucas did not bother to release a restored version of star wars for its 30th anniversary, and the 30th anniversary of empire will also have no restored theatrical empire strikes back.
I am also fairly sure when 2013 roles around Jedi won't get a decent release either.
So all we have are these books but no films to watch. Thanks to Luca$.
Reading a book like making of empire opens old wounds, that we got the shit Gout in 2006 in ported over laserdisc masters in non restored DVD's that they did not even bother to do new anamorphic transfers for.
For one of the greatest sequels ever made, and it gets this treatment.
