"The music is the key to many scenes in episode 9. Prior to the scene of the car bomb explosion, the show focuses on Cromartie when the song mentions the “man who comes around”. Cromartie is victorious in his battle against the FBI SWAT team, and he does decide who to blame, the agents he kills, and who to free, Agent Ellison. When the song focuses on the rider on the white horse and on the man who passes judgment, we see Cromartie's face.

The scenes just before and during the car bomb explosion are keyed to the music as well, and John Friedman said so much in at least one interview (unfortunately, I have forgotten the URL). When the lyrics read , “And I looked and behold a pale horse”, we see that Cameron looks at sees Sarkissian. Here, Sarkissian is the “pale horse” and its rider, and it is Cameron who beholds him. The lyrics continue, “and his name that sat on him was Death”. Next, the scene goes immediately back to Cameron's face. As she turns the key to start the Jeep's engine, we hear “and Hell followed with him” just before the explosion.

Here, “hell” following with him refers to the explosion of the Jeep when Cameron turns the key. Sarkissian, not Cameron, is “death” on the “pale horse”. This scene holds the key to Cameron's fate. As a Terminator, she would not be killed. But the fact that her attacker is called “death” and the bomb explosion is called “hell” would imply that she is heavily damaged. At least for the time, Sarkissian as won.

This is supported by some of the comments made by Josh Friedman. Quoting from one of the interviews, “Anyone who was worried that we blew her up at the end and she is not coming back, I will assure you she is coming back eventually at full force. She’ll still be purty. That’s one of the hard things with Summer, you like to beat her up, but you can’t do it too much. That car bomb, however, will definitely mess her up.”"

"I just watched a trailer for season 2, and I think that while the explosion didn't affect Cameron cosmetically, it it damaged her programming or something. In the trailer it shows her pursuing John and Sarah, I think."

"Cameron will be Allison from Palmdale for now which means yes, she will be VERY different.
But, we will get to see the 'breaking a Terminator' when she disappears and Cameron comes into play.
Or, if the writers don't feel like taking that journey (I really hope they do), then there is always Cameron (as Chromarty) gone to the future without John. But it would be weird and I hope Chromarty goes off and kills Cameron while she is still in Terminator mode and they can switch chips (With John's help).

Why switch? Um... because she's special. She said so herself.
What makes her special?

Well the easy answer is, She is a modified version of the T100 (But still better or around T-888) than can eat so she can get by the security to get close to John. Plus dogs don't seem to mind her as much.

The far cooler answer, which we are are hoping for, is something a little bit out there. Her chip has unlimited memory so she develops a conscious mind or another AI similar to Skynet (assuming there is a difference between Skynet and your average Terminator). That, and she can poop."

"Cameron isn't Allison Young. Fact.
Cameron and John Henry (not Cromartie) are sharing space in her chip while walking around in his body.
Cameron will find a way to separate herself from JH and return to her old body."
