Not to get too far off topic, but there was indeed more planned for the add-on, including a Broken Valley type region. Given the time and resources available, it was decided the game as a whole needed more of a city hub with quests than another open area with exploration, so that region was cut.
The screenshot with the signpost was from a test level early in the development process.
I liked the D2:ED ending, actually.
Do you believe baldur's gate 3 will plan to have dlc races or if they did add new races it would be a free update
