As i can see them skipping Krennic and Tarkin, i'm having a hard time figuring out why they would not release a Cassian. He's front and center, the first hero appearing in RO and Jyn's partner for most of the movie. It would be a terrible let down if HT were to not release him. Besides, they'd have an easy exclusive poping the HS on a Imperial uniform for any convention/event taking place next year.
