Is a pic of the (unfinished) world map: https://www.taleworlds.com/Images/Blog/blog12_west.jpg

Taken from the last blog of Talewords ( https://www.taleworlds.com/en/Games/Bannerlord/Blog/14 ):

"Bannerlord shares the setting of Calradia with Warband but takes place 200 years earlier. The map is also expanded to include regions further to the east and south of that in previous games, resulting in a map which is around three times larger."

So the already big map of Calradia just got a lot bigger, yay!
