Mark Newbold of Jedi news is a friend of mine, you can trust him.
the only definiate scoops now, are Palpatine, and Kenobi's return
Mark, and his team have solid Lucasfilm connections, also you can trust Drew McWeeny's Star Wars coverage. The ST, is tied into the OT< PT< TCW, REBELS
the Star Wars comic by Brian Wood, as well as the Darth Vader TV specials.
Kenobi, by John Jackson Miller, is connected to it, as are the Empire, and Rebellion series of books, Maul Lockdown, and in a sense the Plageuis book, since George Lucas helped with the writing. Kasdan has been working with Kinberg on linking Rebels to the spin offs, and ST, he has also been coordinating with Randy Stradley, on the new comics, and Jennifer Hedle, on the books. their are even hints, in the new toys that have been released, since Bad Robot, and disney added their people to Lucas Licensing.
