One thing I'm a bit worried about is that with all these re-imagining of the Republic and Confederation, is that the prequels could turn into a giant de-construction of the Star Wars concept. The original trilogy was a good versus evil story, where good wins. The prequels are a good versus evil story, where evil wins through deception. In some ways it was a deconstruction of the original, but ultimately the Jedi were still fighting for right, and the seperatists were bad guys.
In the re-imagined prequels that are coming out of these discussions, it's a story entirely of grays. The good guys aren't really good, and the badguys aren't really bad. They're just a bunch of thugs trying to manipulate and subvert each other, and at the end of the day no-one wins. It might be a more mature, consistent story, but is it too far removed from the original trilogy, where it was the righteous rebels fighting against oppression and tyranny? Thematically, does it make sense to go from such a complex story with such a muddled sense of morality, to the simpler, black-and-white themes of the original trilogy? Granted, it's already that way to a degree, but are these proposed changes an improvement, or are they only further distancing the PT from the OT?
