I'm of two minds.
ONE: Lucas himself tried to get a live-action TV series off the ground numerous times, only for it all to blow up because of budget reasons. It's not going to be like any other show. There won't be many opportunities to shoot on-location, and even when there are, sets will have to be built there to make everything look right, which is the same with every other set. Not to mention special props, alien costumes, droids, spaceships to scale, other special effects, etc. EX-PENS-IVE. A sitcom revolving around Dexter's Diner wouldn't be that hard to do, since they could reuse the same set every episode, but I doubt that's what they're going for.
TWO: Agents of S.H.I.E.L.D. exists. While it's set in contemporary times, which eases the burden on the costume department, the show has lots of your typical MARVEL elements, and they make them work for the most part. It's proof of a show that can work on a TV sized budget but still feel grant like it's movie counterparts.
We know it'll air on Disney's 2019 streaming service, so that might give it more of a budget to work with than an ABC show, which means it could have more opportunities to go big. Since it's Star Wars, Disney may also just give the producers a blank check and say have fun. Doubtful, but possible.
Also, I wonder who the showrunner(s) will be? I'd love for Dave Filoni to head the series since Rebels is wrapping up, but he's very accustomed to the animation world, and what's the LucasFilm animation team going to move onto next? Will they finish up the long-shelved Star Wars: Detours (they have like 30 finished episodes or something...)? Will Filoni and co. kickstart a new animated show? It's been confirmed Thrawn survives past A New Hope, so maybe the next animated series could be called Star Wars: Heir to the Empire, and be an adaptation of the Thrawn trilogy. It'd be set after the Aftermath books of course, with some toddler Ben Solo stuff, canon Mara Jade (if possible after The Last Jedi, who knows what Luke's backstory will be like), and a big component could be Thrawn trying to reestablish the Empire while other remnants skulk off to form The First Order, and their clashes on how to proceed. That could all be interesting.
I'm not sure I'm excited or not for this, since we've been promised a live-action show before and haven't been given anything except whispers about what went wrong behind-the-scenes. I'll need more information. Like with this new Trilogy, it's just something I have logged away in my head in the "Oh yeah, that's happening" category with the Respawn game, the Bioware game, the Obi-Wan solo film, and Episode IX. They're too far away at this point to think much about.
