From another review of the DVDs:
"There’s lots of great behind the scenes footage that we’ve never seen before and some DVD quality transfers of shots from the movies that have been cut and replaced in the Special and DVD Editions."
Now, it doesn't say how much is there, but there might be a begining of the "ultimate edition" which has been batted around here lately, assembled from the official DVD transfer, and inserting original shots where appropriate. Something to get our hopes up for, I think...
