Reading the whole thread would be too punishing, but the news confirming Abrams seems to be a slightly more promising avenue for discussion than the Highlander franchise.
Abrams can be disposed of pretty quickly. Directors as such, despite the conventional wisdom, are not the primary creators of movies. This is fortunate, because Abrams, desite his buzz factor, is at best second rate. People who say otherwise just aren't thinking.
The really interesting news is the screenwriter who has been hired. His name is Michael Arndt. His resume includes Little Miss Sunshine, Toy Story 3 and the unreleased Oblivion, an SF action movie with Tom Cruise. And Hunger Games: Catching Fire, which I think is the sequel to the uncolonized Hunger Games.
Obviously the ability to write dialogue displayed in Little Miss Sunshine and the ability to handle positive emotions and ideals without sniggering displayed in Toy Story 3 are quite positive signs in regard to handling a Star Wars movie. Arndt getting fired, with this track record, would be a very bad sign.
But Oblivion should be very interesting in regards to showing how Arndt can combine world building and plotting along dialogue and theme. The original trilogy I think worked so well because it had Luke Skywalker/Mark Hamill (yes, yes, a dissident opinion) and the prequel trilogy suffered because it focused on the villains. Given the contrast the way for them to go is to center any new film on a hero. A real hero, not an Abrams figure.
Also, whether the new movie is a sequel to the original trilogy or an interstitial untold story, either the story has to be so dramatically tight, taking place within a few breakneck days. Or it has to make a believable background, build a Republic, old or new, that make the characters' actions meaningful. This will be difficult, because Star Wars is a notriously soft version of scifi. It caused problems in the prequel trilogy when Lucas needed to have real stakes for the characters, and they were flailing around a fantasy instead.
