I still want to say that the escape pod shots are from the '04 job. I remember that shot of r2 and 3po as one of the big "before and after" examples from back then. Of course, that doesn't mean they're not simply using the exact same scene to show off their work on the newer restoration, but the voice-over guy does say "here's what we delivered for dvd."

Also, it's from a different demo-reel, one that contains a lot of older restoration jobs. The reel with the saber and trench run and luke/vader fight from Empire (and that shot of 3po from ANH tip-toeing up to the camera) doesn't have anything from before 2009. That, combined with the fact that the footage doesn't match up to the blu-ray (aside from the sabers not being the originals), is what makes me think it's the 4k scan. I think they've simply redone the sabers yet again for this new scan since it was probably done primarily to make a "finished" SE and a starting point for a 3D conversion.
