What's blowing my mind (and I'm surprised no one else has mentioned it so far) is that in the newest set of expanded cockpit shots Ady posted, it's not just the cockpit walls that have been expanded -- we're even seeing more of the characters! There are two shots, for example, where we actually see more of Han's body than in the cropped version.
Not only will this be cool to watch, but it would also appear to mean that Ady isn't extending our view of an inanimate background (by stitching still images together and motion tracking the extra pieces in the shots), which is what I had originally thought he might have been doing -- but actually using (and restoring, since it sounded pretty beat up) the HD film scan, including the actors' performances. I wonder if there are other hidden gems that have been restored from this asset, as well!
