It has potential, in telling a 9-episode saga in the similar way the original nine-lology (sp?) was planned. But the problem is the time gap was so great between each trilogy, only the "common aesthetics" and "it's all Star Wars" will tie them together. Given the prequel and the final three Star Wars movies had been handled I don't have high hopes, but I am willing to change my mind.
I think the franchise did a good job in continuing to build upon existing IP, letting the new series be continuation of Star Wars: Rebels, and other continuations, and actually bringing Heirs to the Empire to screen as official canon, but I am NOT quite as certain about them going into lore CREATION territory.
