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.
