Well, yeah... being that this is the first time the films have been (commercially) available on a 1080p HD disc with the ability to display/hear them via HDMI. But no extra money or effort was put into any additional restoration or even to fix the color timing issues they goofed on for the 2004 release (of which the same masters they used here).
Also... they've been showing the movies in HD on TV for a couple of years now.
In other words, yes... they look/sound sharper than the DVD releases. But that's not because of any additional time, money or effort. Trust me. It's only because of the fidelity of the format. A dog with a note in his mouth could have achieved the same results.
A lot of us are actually much more pissed about the lack of effort put into new/correct transfers and sound mixes than we are the silly changes in the movies.
They did redo some of the audio mixes though.

Given that Lucas once said that sound and music is 50 per cent of the entertainment in a movie, remastering the audio soundtrack has been key to putting all six movies on an even keel. This job was given to Matthew Wood who has been working for Skywalker Sound for 21 years, with a number of those years spent sprucing up the Star Wars soundtrack for a hi-def release.
"It was a long process; I started working on A New Hope around the same time as the DVDs were released. I was already preparing the soundtrack for some sort of high-definition release around that time," said Wood to TechRadar, minutes before he previewed the soundtrack to us straight from one of Lucasfilm's mixing desks.
"[George] Lucas loves sound; it is very dear to his heart. Skywalker Sound is actually at Skywalker Ranch so we have a very close relationship."
The soundtrack has been given a massive makeover by Wood and his team. For the first time we get to hear the movies in 6.1 DTS-HD MA, which has meant some hefty tinkering for the Original Trilogy. But with help from Lucas and a surprise find in the archives - production roles from 1976 - the audio re-fresh is how Lucas originally intended the movies to be heard.
"I wanted to make sure that George for the original trilogy was hearing what he heard when he first made the films, as we're remixing for a 6.1 format, so he spent a long time with us making sure it was right," said Wood.
"On this Blu-ray release one of things that came available to us that we found deep in our archive was the original production rolls.
"These were the rolls that were used for the original dialogue recording and the entire production recording that were done on the set.
Working from such an audio record was a special moment for Wood – a lifelong Star Wars fan – but it was also key to picking up audio cues that had been lost over time.
"These [production rolls] had only been played once, the first time they were used they were transferred to magnetic film back in 1977 and that was cut.
"So I got to take them and retransfer them into the computer and with the highest quality analogue to digital converters I could actually re-sync these back into the original picture. That is one thing that is new on the Blu-ray. It's amazing."
Wood also emulated the recording processes of the time so as to not lose the magic of the soundtrack, borrowing some of the tricks used compiling the original soundtrack to his benefit.
"When I think about what was done with the mixes back in '77, and I was talking to Ben Burtt [the original sound designer] about this, they were working on Star Wars on the night shift, as that was the only way they could get time on the main stage and mixes were done like a performance.
"The entire reel had to be mixed at once. You had somebody working on dialogue, someone on the effects, with all the tracks coming in synchronized from magnetic film machines which were very loud.
"And you have to remember all your favorite moves and what dialogue comes up and your EQ, and it is all done live. I have always found that fascinating and I always want to make sure that I hold on to that performance, because it is a performance.
"We have that mix and are constantly going back and forth and making sure that we are getting that and at the same time trying to expand it for the modern soundstage."
The demo we were given of the audio was exhilarating. Watching Darth Vader in the carbon freezing chamber in Episode V, it was the soundtrack you know and love but it fizzed with extra detail.
