ABCmedianet I believe has a synopsis saying Vaughn and Syd survived the crash and that she's preggers with his child. Here it is acturally:
Even more gripping and emotional events are in store for Sydney. After they both survive the crash, she learns that the man she has known as Michael Vaughn is under investigation and suspected of being a double agent. She questions whether their business and personal relationship over the years has all been a lie. When Sydney discovers that she is pregnant with Vaughn's baby, she's determined to uncover the truth about him. Meanwhile, because of Jack's past betrayal by Irina, he begins to worry that his daughter may suffer the same fate as he did. He will also have to deal with the fact that he will soon become a grandfather - while still learning how to be a dad. Sloane will have to do some soul-searching of his own, as he makes an unholy alliance in his desperate fight to find a cure for Nadia - who is still in a coma.
New agents will be introduced and a nefarious organization will come to light in Sydney's life as she fights to protect her unborn child -- all the while traveling incognito, outsmarting the bad guys and keeping the world safe.
"Alias" stars Jennifer Garner as Sydney Bristow, Victor Garber as Jack Bristow, Ron Rifkin as Arvin Sloane, Michael Vartan as Michael Vaughn, Carl Lumbly as Marcus Dixon, Kevin Weisman as Marshall Flinkman, Rachel Nichols as Rachel Gibson and Élodie Bouchez as Renée Rienne.
