I picked up the Star Wars movies on Blue Ray yesterday, the "Complete Saga" set. The set as a whole is amazing, though there's some omissions in the extras department. It comes with 3 bonus discs, one of which has several documentaries, but the "Empire of Dreams" documentary is missing (included on the DVD release of ep IV-VI boxed set), and I think there are a couple other documentaries that should have been included as well. Fortunately I still have that bonus disc so I can watch it anytime.
I've watched the movies in order but had to stop after Ep IV, so I still have ESB and ROTJ to go. I am impressed, they all look great in 1080p on my 40" HDTV. I also watched some of the special features, including some of the deleted scenes, some of which I had never seen before.
