I believe Ady was still working on the Emperors dialog with Vader when he posted the last clip. The FX work was complete, it was down to one word that ady was trying to find resources for. He was trying to find Ian saying "LUKE" so he could restore the original line that the Emporer spoke when referring to Skywalker. Originally the Emporer said "Luke Skywalker". But for the 2004 special editions it was changed to "Young Skywalker". Don't know If Ady managed to restore the original line or not.
