8. The Entire Old Republic
After Bioware's fantastic Knights Of The Old Republic RPGs, The Old Republic would explode into something of its own separate brand, with its own novels, comics, and reference books creating an incredibly rich history of an early Star Wars universe that was so different both socially and politically from the one that we came to know and love that it could easily be an entirely different series. While Disney are unlikely to visit the ancient history of the Star Wars universe anytime soon on screen due to the fact that they seem to think that people are only interested in seeing familiar characters and settings, it won't hurt at all to bring the whole of the Old Republic back into the canon through other means. As it's all ancient history, it really can't affect the plots of the new films in any way, like many of the other EU stories would, and it would be great for the stories of the ancient galaxy that fans love so much to be bought back. On a side note, The Old Republic MMORPG is still getting updates, which are now the only new content in the EU continuity. Hopefully Bioware will continue to add it for many years to come.
