If someone with math skills wants to track the figures over the next day or so and give us a rough estimate of when they estimate the map should unlock, we won't hold it against you. Once "Coral Sea" opens up, if should include an "Air Superiority game mode." Get killin', folks, who knows if there'll be another carrot dangled in front of us when this challenge is done. We hope there will be.
