I haven't heard anything about that, since the conversation concerning this information was only about the three English mixes. But I believe Lucasfilm has been digitizing many of their stored materials, so it's at least a possibility.

Were the English mixes restored during creation of the new Blu-ray mixes? In that case I'd have high hopes for the foreign dubs, since at least the German dub tracks (the raw voice recordings) were freshly digitized for the Blu-rays, with audio quality now pretty much on par with any modern film production - not as muffled and tinny as they sounded on every home cinema release that came before.

It would be awesome if they'd re-construct the German 1978 mix using these.
