I really don't see canon doing a paid upgrade on the c100 markII. I think they will continue to over charge for a 1080p camera until the market flat out demands 4k. I know alot of people are saying 4k is so far away but I am not buying that at all. I think tech is picking up at a huge pace and we are going to see 4k get here faster than we think. With that said, shooting 4k and editing in 1080p is awesome, I find myself grabbing my gh4 over my c100 all the time simply because of this factor. But everyone shoots different stuff and some people on here and making a full time living with their camera and 4k does not matter at this point. What ever makes the most money TODAY! thats the camera I would get. But no 4k for c100 mark II, thats just wishful thinking.
