Even though that trilogy is no longer part of the Star Wars canon, Disney and Lucasfilm decided to bring Thrawn back to the canon, via Star Wars Rebels and Timothy Zahn’s new books.
It looks like we’re getting a whole lot more Thrawn in the new Star Wars universe.
He only recently appeared on Star Wars Rebels season 3, which was met with a very positive response from fans.
Del Rey later confirmed the news on Twitter, via the official Star Wars Books account.
