Kind of curious what it'll feature. At this point in Disney's canon, the New Republic is around, the Empire is no longer a threat, the First Order is just really getting started, and Ben hasn't gone dark side yet, and he's young and presumably still with his parents. Luke I'm guessing is probably just collecting Jedi relics or something.
In the old legends timeline this is the year that Luke began to rebuild the Jedi Order, however I can't quite see that happening unless they somehow recast a younger post-ROTJ Luke. When Lucas was considering his own live-action show, it's said that he was thinking of shows like The Wire....perhaps like Lucas intended, maybe we'll get a sort of Star Wars Crime Drama, which, while an element of the films (Certainly with Han's past), was never really their focus (Although I imagine Solo will deal a bit with it).
