The Rumor started when the last episode of Gundam SEED Destiny Aired that Sunrise was slating for a third continuation of the CE timeline. Three "Plot spoilers" were released stating:
"Gundam Seed Eternity-Episode 1
Two years have passed ever since the war in Gundam Seed Destiny. Peace have restored till Lacus Clyne the chairwoman of PLANT was assassinated. Chaos then began as it created unrest in the people of PLANT. Kira Yamato was very agitated when he found out that Lacus is dead. He swore to find the murder. And that’s how the war began again with an unknown force planning to take over PLANT. While in Orb, the new main character could be seen learning how to use mobile suits.
Gundam Seed Eternity-Episode 2
Two years have passed ever since the war in Gundam Seed Destiny. Peace has restored. Until Cagalli, the Orb’s representative disappeared into nowhere. Someone mysterious then took over her role and started to wage war with the other countries. What has happened to Cagalli and now that this person took over the role, what’ll happen to Orb?
Gundam Seed Eternity-Episode 3
The Earth Alliance has returned with main character, Kei Minato and starts to attack the other countries. Both Orb and PLANT tries to stop it from invading but fails too. Kira Yamato had no choice but to go to war once again but this time, with Shinn Asuka and Athrun Zala. They finally defeat the Earth Alliance but as an unknown force approaches them, what’ll happen to Kei Minato who is part of it? "
After the fact many fans swore it was the truth and Sunrise would not deny a third series in production. Fake fan art spawned shortly after such as "Gundam Eternal Freedom" and blogs went insane making other "spoiler" material such as the gundams of "Kei Minato"'s Team.
Gundam SEED Stargazer eventually the third CE Series Sunrise planned for(it was actually an ONA/Movie/OVA) that was centered around an Earth Federation Mobile Suit Team.
The Speculation soon died afterwards. However some fans have sense made Fan Fiction set in the CE universe.
