I think Sting might be the only one left in the end, so far he's had nothing to make him interesting...Meaning he's gonna live.
BTW I come baring spoilers! All of these are confirmed and will happen...And I cleaned up the sloppy English to make it easy to read.
So, don't read ahead unless you wanna be spoiled
PHASE-33: The Fallen Wing of FREEDOM
Knowing the great destructive power of the Destroy Gundam and unable to defeat it. Kira is forced to self-destruct Freedom. Despite the great power of the Destory, it is unable to withstand the blow, nor is the pilot. Shinn watches in horror as memories of his past come flooding back to him.
PHASE-34: The Foolish Mistake
Remembering what happened two years ago (the death of his family) Shinn realizes that Freedom was the cause of their death. An enraged Shinn takes on a badly damaged Freedom.
PHASE-35: The Crimson Knight Justice
Just as Shinn is about to strike the final blow Athrun appears in a new Gundam. The Dark Justice(WTF?!) was given to him by chairman Dundal. However unlike before, Athrun sensed something more, and uncovered the plans to build the Destroy.
PHASE-36: Memories
Athrun and Kira locked in battle once again(I'm assuming somehow Super-Freedom is already here). Neo comes to a realization about the truth of Gilbert Dundal wanting to produce Destroy with him. Neo tries to remember his reasons for wanting to defeat ZAFT but is unable to remember. He returns to his room and uncovers a picture of Archangel captain Murrue Ramius. (told ya' Neo was Mwu!)
PHASE-37:Goodbye
After fully restoring his memories, Neo decide to escape from EA. As he escapes he is found by EA soldiers and thrown in jail, but the Archangel makes it's decent.
PHASE-38: The Shining Wing of Justice
With a new passenger escaped from EA, Archangel makes it's way off the scene the previous battle. EA is unwilling to let Mwu go that easy, they send a rebuilt Destroy Gundam to defeat the Archangel. Dark Justice appears and defeats the Destroy. Marking the return of Athrun to the Archangel.
Sting is now the final Evident left at the EA base. Elsewhere an unseen force learns of these events, they being planning for project "DESTINY" . Sting and Rey (from Minerva and the EA base) are seen looking up at the sunset.
Stellar is killed in 33.(Shinn does the Cloud thing to her body), which means the Destroy will be at least out of comission for a while. It`ll probably be like the Psycho and Psycho mk.2 in Zeta.
Also, I think Rey and Sting might get some good story in. It mentions them looking up to that sunset right after the "unsee force" bit.
