So in case you missed it, the Costco Connection, a magazine sent to members of the warehouse store, scored a scoop from Lucasfilm exec Kathleen Kennedy.
“The Saga films focus on the Skywalker family saga. The stories follow a linear narrative that connects to the previous six films. The Force Awakens follows Return of the Jedi and continues that generational story. The Anthology films offer opportunities to explore fresh characters, new storylines and a variety of genres inside the Star Wars universe.”
So on one hand, yes, there have been rumors since the very, very beginning of Star Wars Episode VIIthat it would center on offspring with Skywalker blood. Before the Expanded Universe was officially decanonized, many fans (including me) said, “Oh yay! We get movies about Jacen and Jaina Solo!” Who are Han and Leia’s twin children in what’s now Star Wars Legends.
