Mind you, not exactly a shocking revelation here - but there's a GM screen coming too.
Interestingly, there's this tidbit:
What’s more, the GM Kit provides guidance for linking the adventures included in the Core Rulebook, Star Wars: Age of Rebellion Beginner Game, and the Star Wars: Age of Rebellion Beta to the Dead in the Water adventure in the GM Kit, so you’ll be able to create a larger narrative in the form of a continuing campaign for your players.
So a three part starter game? That's kind of cool. Mind you, much like Crate of Krates, you wont be able to get your hands on the Beta game after - oh, about 6 months from now. But it's still a keen idea.
