"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."

We agree on a few things, the rest is up for grabs.
Cameron is not Allison Young, true.
The actress Summer Glau (not leaving the show) will be Allison from Palmdale until one of the hypothesis come true.
Cameron and JH (It was reference to his body, forgive me) probably are sharing the chip but logically there is not reason for it. The T1000 was from the future and they are back to the future. What was achieved by John Henry's creation in the past? That is why I say that John Henry has to stay put.

It has already been said that any change would change John Henry's personality let alone a complete dump into a new environment. Now, if there was some gain from John's altered personality then I would very interesting to see where they would go. I was merely suggesting the possibility.

Cameron will find a way to return to her old body. This is another point of agreement. But, I believe they will find out how Allison will work out but ultimately will settle her back as future Cameron or old Cameron.

1. Yes.
2. She'll be in it, but her story will be in the past until John returns.
3. Sure.
4. She jumped forward because she knew how important John Henry would be to the war effort and John's survival.
5. No, the events in the past happened BEFORE the events in the future (figure it out).
6. Cromartie was destroyed. His body is all that remains.
6A. I doubt Cameron is an errand girl.
6B. Again, Cromartie is dead. John Henry is the A.I. you're referring to. And no, he went with Cameron (on the same chip) to the future.
6C. Yep, pretty much.
