To answer the OP, there is no possible way our new regime moves on from Cam. Take it to the bank, Cam will be behind center in 2013 for the Carolina Panthers.
I would say that it us slim to none chance that Cam is not under center next season. It would be highly unlikely that they would not at least be intrigued enough to see what Cam would do in their new scene. He had too much talent to make that knee jerk decision.
However, I have seen stranger things happen with both a new GM and HC.
Likely....no way. Possible....anything is possible.
