Sujoy, I know the age of the cameras you mentioned are way off... I wanted to be little accurate, so YES, I checked

They announced a version called 1Dc just 6 months after 1Dx. But I don't what's the difference between the two cameras other than the name.

May be they just named new and upgraded the firmware fixing some bugs
Anirban, FF means Full Frame.

Sorry for the confusion.
