Through jedi_news, I saw a link to this piece on the future of SW:
http://www.thedeadbolt.com/news/104510/futurestarwars_feature.phpNow here's what I think.
It is definitely true that the television shows have the power to radically change fandom from the way we know it now. Even the books and comics have to some degree changed fandom and those are not going to be on the same level of "canon" as these television shows will be. They will reach far more people than printed EU has and there's no reason why Clone Wars or the live action show cannot be just as "canon" as the films.
Aside from theatrical launches or occasional theatrical re-releases of the six films, most people from here on out will experience SW exclusively on their televisions or their iPods (whenever the saga ends up in iTunes format). Count in video games with more complex plots that will actually be relevant to the canon or EU. Where do you play that stuff? On your t.v.! Folks will start to think of SW as more and more of a t.v. thing with toys, books, and comics to supplement the fun.
The author has a good point about how episodic television will allow more time to explore characters, cultures, and all kinds of other nitpicky aspects of the SW universe that a two-hour movie just can't cover. Just think of all of the wacky stuff that's going to be added to our idea of SW thanks to 13-20 hours' worth of programming
each year. Many fans' heads will explode! We'll need a whole Jedi archive just to fit some future edition of the Star Wars Encyclopedia.
The SW universe, whether Lucas intended it to be so or not, is probably the most vast literary/imaginary playground ever created. Yes, even more so than Tolkien's Middle Earth. SW's adaptability to emerging media formats is key to why this is the case. There are many, many stories to be told in any era; the EU and canon combined spans over 10,000 years!
Nevertheless, the Skywalker story arc will remain the heart of the SW universe. It's what sold people on SW in the first place and I think that KOTOR notwithstanding, they're going to find it's hard to stray too far that core mythos without most regular folks losing interest.
