If all those rumors are true, it looks like instead of a glorious restoration of the Republic in the galaxy, the general treatment follows something of the history of western civilization, this trilogy being the Middle Ages of the star wars universe.

A disorganized "federative" (feudal) system where the [Western roman empire] Empire was beaten by the rebels, and a fully alive Empire in the remnant rim [Eastern roman empire]. All glimpse of old "pagan" religions, both Sith and Jedi, banned and replaced by something new; technological stasis in the upper social spheres, while involution in the lower ones, the everlasting issue of the limit between the Empire and this "federation"...etc. Crusades? Qu Ran rising?

Just a thought tho; I'm not sure if that's a treatment i would be interested to watch, but why else would the characters be amazed at a lightsaber, Luke a fugitive, the Empire fully alive and well (chrome troopers are quite a luxury).
