Not sure if anybody cares but when NFP was announced, I made some predictions on my page regarding which civs/leaders might show up. The prediction was based on civforum polls, since this is a huge source of inspiration for devs over the last 3 years of developing civ6. One of my prediction is that in pack 5 (the pack with the alt leader), we will have Vietnam and Kublai Khan leads China and Mongolia.
Guess what, after the Ethiopia update this morning, someone found Kublai and Vietnam in the game code!!!!
I am SOOOO excited for January :)
