According to a post on Reddit by Ubisoft's head of content Aymar Azaizia, an Assassin's Creed TV series is coming.
Azaizia said this regarding the content of the show: "It's like the movie guys, we will take our time, to get sure we deliver something we can be proud of, but if you wander if it's on our plan... YES." Do you think it will be the same level of quality as the film?
