Same tbh, the devs stated it would be a visual overhaul of the map and that we can move our lair locations, noting more.

Now with the new map here, there is a ton of potential they can do with it, like change it if major events happen in the lore etc. see luminax roaming around

Also I am pretty sure the Sactums will play a pretty big role in the future in the lore and the map will reflect that if something happens with them.
