Based on the quote "The game is set in ninth century Iceland, so we've been sending our art and audio teams out there doing photography, photogrammetry and combining it with satellite data to recreate large swathes of the landscape." and him saying they didn't want to make a sequel and to do something different it sounds like they can be going in an open world direction for the game. At the very least much larger open areas akin to TLOU2.
