Ha! In typical Lucasfilms fashion, the Original Trology will NOT be available for individual sale. Instead you will need to purchase the full 6 disc set of both Orginal and Prequal trilogies in a keen $90 package. Also add to that the fact that the "DVD's" will be cut and paste jobs of the Laserdisc versions and you have a half assed way to snatch more loyal fans money.
Unofficial of course but PA is usually reliable with their dirt.
