Hey Mike,
I did not see you there. You are correct that not all of the flavors will be available at first, and likely only one ProRes version in the first cameras released, so I have heard the same that you have also, but the camera there at the booth was showing all 5 versions ( 4444 to Proxy) in the menus.
Did you go over all of the menu outputs listed? I asked a couple if they were all accurate as there were couple of odd ones in the list I am still trying to understand what the output labeled as 1.5G 444 could possibly be.
