FROM revealed there are 6 lands with 6 demigods as your target.
All of the map shown in the gameplay trailer shows what seems like 2 of them, while the CNT covers between 1/3 and half the southern area leading to Stromvale and Godrick - your first "great rune".
The main "dungeon" in the area above it to the north-west is most likely the "blue" castle "straight out of bloodborne" also shown in promos, in the middle of the forest valley.
Then there is the volcano/mountain place home to the thunder tossing dragon.
We've also seen screenshots of the "winter" place, that could be far up north. The "atumn" place, also seen in the gamepay trailer, might be part of the volcano area due to a similar palette - likely starting to the East of Lingrave also due to the corresponding color palette of the map.
