I can’t believe BB is not providing this information. In the U.K., this item is available from Amazon. To see a full description in your Amazon app:
Pancake menu> Settings> Country & Language> Change Country/Region to United Kingdom.
When you return to change back, you’ll find a new option to quickly return to your original country.
It appeared to me the 1977 version of A New Hope is not included, and I’m not surprised. It’s Marketing 101 to hold the originals and the Ep I to IV 3Ds for future upsells. (pre-Mouse, Ep I 3D was theatrically released and II 3D was shown at D23. Therefore, at least Ep IV 3D likely exists, if not all four. Wouldn’t George have commissioned all six on a cost basis?)
