For me the stage presentation was a complete and utter wast of time (I think I fell asleep for a few minutes). I had the feeling that most of the people in the audience were amatures or noobs who did not know much about photography and the EOS system.
The show and touch session after was a bit better, but nobody could answer any of the three main questions I needed answered, so no supprise that nobody could tell me how the new 1DS MK3 compares to a 16mp digital back on a medium format camera.
I think the mistake was mine in expecting something more then it was.
