A:Answer Your question is a bit confusing when you wrote it out, but I will try and answer...
There are the entire 9 Star Wars movies from the Skywalker Saga. Episodes I - IX.
Each movie has 3 discs, a 4K UHD, Blu-ray/Blu-ray special features, plus a digital copy. 27 Discs, total.
"ROGUE ONE" and "SOLO" will NOT be in this set.
You get the special box with the artwork and a letter from Mark Hamill, which does NOT have his original signature. It is a copy of it.
I am sure the special features will have what was previously brought over from the other releases already out.
Hang on to the 2011 Box Set that came out with the 9 Blu-ray discs, 3 of which were special features if you have that. It was re-released with Darth Vader on the front cover.
