I’m sure Team Blu will probably have the 5.1 in their version, as their goal (to my understanding) is more about having the best presentation of the original version on blu ray, rather than trying to accurately present exactly what was seen and heard on 35mm film in theaters.
We will do the Original Trilogy up the absolute best we can with all the best resources available, we have assembled the best Team for this so stay tuned! we are just trying to clear our plates and I am going to need to do what Harmy did a while back, I need a PC rebuild very soon for all this stuff we have in store, so hopefully when ready I can get the same support Harmy did, he and I will spread the word when ready.
Exciting times are coming!
