In addition to the
aforementioned Mace Windu series, Marvel Comics will be producing a Cassian and K-2SO one-shot by Duane Swierczynski and Fernando Blanco. It is a prequel to
Rogue One (duh!), and "will reveal how Cassian, one of the top intelligence officers of the Rebel Alliance, met K-2SO, a reprogrammed Imperial security droid." Expect more information with the August solicitations due next week.
