it's a newly restored high definition transfer with DD 5.1 audio.
There's a simultaneous BluRay release so I guess they sort of had to do a bit of work on it.
Some new extras, some interesting old stuff they dug up, etc.
It'll make a nice companion to the 2-disc S.E. Holy Grail and Meaning of Life releases either way.
I just wish they incorporated some of the missing scenes themselves. You've sort of spoiled us with your version.
Anyway, no word if the deleted scenes have been restored or not though.
