Take for example Lord of the Rings Online’s Northern Mirkwood map, which testers have accessed during the Update 22 beta. It shows a truly huge zone that is divided between the dense leafy forest and the eastern Dale-lands. Not only can you get a sense of scale here, but also there are many tantalizing landmarks on display for future exploration.
YouTuber Andang took fans through this map and its highlights while moving on to the new larger Rhovanion map that might contain clues pointing toward future zones and expansion. He notes that Northern Mirkwood is truly disconnected from any other zones (being situated far north of the existing Southern Mirkwood) and that it has map markers pointing toward regions like the Iron Hills, Fields of Celduin, and the Mountains of Mirkwood.
