Funcom has stated officially on a number of occasions Onlyillusion, that there will be no new land added to the map. The reason given is that much of the unused land is for dungeons (There are at least two more to come) and the engine is at the limit of what it can handle. However, some debate does exist surrounding this. You can read a very good discussion on this subject in the thread below if you are interested. I personally would love to see at least one more biome added before Conan Exiles calls it a day, and even devised a concept biome myself (The Black Marshlands ‘Bog’ biome; second attached thread), and am putting together another two in my spare time. So dont get your hopes up tooo much ok, but there is a very, and I do mean very small slither of hope.
