Has anyone wondered the REAL reason why Chaos is not in Dawn of War 3, despite the large fanbase (both those who want to play and those who want to purge them)? Now here is your answer: because all of their known characters are dead. Sindri, Bale, Crull, Carron, Araghast, Eliphas, Ulkair and Kyras - not a single of them made it out. The only exception is Abaddon, but he is GW-cannon. I know some of you want Eliphas back, but he has only fewer failures than Abaddon himself, so unless Abaddon wants Eliphas to even the score, we are probably not going to see him again.
Both the Eldar and the Orks have popular characters who did indeed survives, so naturally Relic wants to attract the fans by having them back, even if throwing them together makes no sense whatsoever.
Regardless, which Dawn of War characters do you want to see again?
Imperial Guards: Vance "Motherfucking" Stubbs definitely lives, as does Castor and Merrick. These are the victors of previous games. There is also Mira from Space Marine and Colonel Brom if you ignore the novel.
Eldar: Caerys is still kicking. Despite her very shallow role in Soulstorm, you can find quite a few pictures of her on Devianart. Kayleth and her commanders are alive and well.
Space Marines: Hair-gel Commander and Thaddeus are now in the Eye of Terror battling Chaos, so we are probably not going to see much from them. Aside from those two, Cyrus, Diomedes, Tarkus and Martellus are still part of the Blood Ravens. Ignore the Ultramarine Chaplain in Winter Assault because he is probably a Blood Raven in disguise.
Tau: Shas'o Kais retreated from Kronus with his life. He is also now GW-cannon according to Tau 6th edition Codex.
No character from the Necron faction remains animated.
Sisters of Battle: The pervy old man whose name I forgot may still live, as he is seen visiting the Sisters' graves in the Space Marine ending.
Dark Eldar: Tahril managed to get away as the Imperial Guards sacked his base. However, he is probably a fugitive now as Vect would not have taken his failure well.
My favourite is Vance Stubbs. I can almost smell him leading the Astra Militarum in the next expansion.
