Mentasm's review on dvdactive seems to imply that the audio is the '93 sound mix, which is not surprising considering these are coming from the Definitive Collection masters. He refers to omitted lines and added sound effects for the first film, which describes the '93. So no tractor beam line or closing of the blast doors, but yes to breaking glass sounds in the cell bay shootout, most likely. And Artoo will most likely not taste very good.
