An article with some details of the 3D work:

Prime Focus set up a process for the 3D conversion of the 115-minute movie, which was mostly done at their facilities in India and in London. It involved at various times 600 of their employees. “Everything was sent back for review,” said Malhotra, “by (the Lucasfilm team) and George Lucas himself. We would get notes from them, suggestions for enhancements and any direction they had. It worked pretty smoothly.”

Still it was an intense eight month process *CUT*

and look who get's quoted:

Michael Kaminski, author of the unauthorized 2008 book The Secret History of Star Wars, who has been critical of Lucas in the past when he changed things in the movies, is on board with this re-release. “A lot of people say ‘3D, oh its crap,’ because there are so many 3D releases done badly,” said Kaminski. “And it’s true. Often the film is done badly. But the fact Lucas is a supporter of 3D and spent a lot of time getting it right, I think it’s a fun way to re-energize the movies.”

Nice catch! Kind of random quote though.
