The show might not ever be made. One thing to remember that TV shows exist to sell ad space for the TV networks that air them. One of the reasons why brain dead sitcoms, mysteries, and cop shows, all dominate so heavily on TV is because they are cheap to make. A lot of them require paying the actors, street clothes, and maybe some prop guns, along with renting shooting locations. With sitcoms they can do something like rent an apartment and then re-use the same set constantly as like 90% of the action might happen in the living room of the average suburban family or whatever. The point is that they are relatively cheap to make, which means they don't cost much for the networks to buy, and then they can sell advertising space affordably to recoup their losses.
Science fiction TV shows and the like require a lot more work to produce. They need to detail the insides of space ships, make props and furniture that seem like they came from the future, and then every time they want to have someone shoot a ray gun or whatever that costs money to do the FX for it.
Writing scripts for a potential TV show is easy, but as was pointed out with "The Phantom Menace" the number of FX scenes George Lucas wanted was crazy for the time. To do a TV show for "Star Wars" and have it look anything like the movies, is going to come down to spending truckloads of cash, and that means that the show is going to cost the networks a lot, and while the "Star Wars" name might carry some weight for viewership, the bottom line is guys aren't going to want to pay the superbowl rates it might take for the networks to recoup losses.
Even allowing for things like green screen like Sanctuary is using, I admit I have my concerns. I love science fiction and fantasy programming, but it's hard to do for a reason.
To put it bluntly in Star Wars we want to have people shooting off blasters, deflecting blaster bolts, and getting into wild fight scenes, but that might be too much for TV. It's sort of like the problem with trying to do super heroes for TV, they wind up having to develop the shows around nobody doing anything super in most of them, because the FX for using the super powers cost a lot of money, having two super guys fight, and doing it well, is a major money scene for Hollywood, and not the kind of thing TV shows can usually handle, and it really shows with the way they have to juggle the plots. Honestly I think that's part of what killed "Heroes", the plots got increasingly obtuse and the character motives ridiculously less believable to work around the issues of anyone actually doing anything that would take FX money.
