In one of the latest interviews, Stoic Studio lead designer Matt Rhoades said they were keen to expand the series in one or another way. He also confirmed that a DLC would be a great option because it was left a lot in the Benner Saga world to explore. The studio didn't announce anything, so now we just wait for The Banner Saga 3 (July 26, 2018) and look forward to more information about Stoic's plans.
