5 unidentified landmasses in IE

From the map, you can see that there are 5 unidentified landmasses in IE. Here are my speculations. 1. Space 2. Genghis Khan and Cathay Korean 3. Elephants and Monkeys 4. Snakes, Tigers, Cats, Furries, and Dinosaurs 5. Sea Elf

What do you guys think CA will fill these landmasses in the future?
