Saw this one when it was a "some guy told me some person from USA Today said that some LucasFilms dude said on the Internet" rumor type thing, but it appears to be official:
This September: Original Unaltered Trilogy on DVD May 03, 2006
Fans can look forward to a September filled with classic Star Wars nostalgia, led by the premiere of LEGO Star Wars II: The Original Trilogy video game and the long-awaited DVD release of the original theatrical incarnations of the classic Star Wars trilogy.
In response to overwhelming demand, Lucasfilm Ltd. and Twentieth Century Fox Home Entertainment will release attractively priced individual two-disc releases of Star Wars, The Empire Strikes Back and Return of the Jedi. Each release includes the 2004 digitally remastered version of the movie and, as bonus material, the theatrical edition of the film. That means you'll be able to enjoy Star Wars as it first appeared in 1977, Empire in 1980, and Jedi in 1983.
Now I'm not one of those rabid, idiotic "ZOMG GEORGE LUCAS RAPED MY CHILDHOOD BY MAKING GREEDO SHOOT FIRST" types, but I always did prefer the look of the original movies to the super-duper digitally-remastered "Let's put in all-new establishing shots with crazy farting CG animals, and shove Hayden Christiansen in as a blue glowie on Endor while we're at it" stuff. So honestly I gotta say this announcement makes me happy. Guess it also means I can finally stop lugging around those VHS tapes I recorded off the Sci-Fi Channel 15 years ago, when they ran all 3 of 'em back-to-back.
