I hope Canon learned their lesson, you can not count on glory of the past, both 5D and 5D MK-II were continous break through but 5D III did not continue the expected tradition of big breakthrough, despite the fact it is a very good general purpose camera, in addition they raised price too high adding insult to injury. I believe the price drop is reflection of buyers power. we are hoping the new camera will at minimum keep or improve good features of 5D MK III and fill in the deficiencies, of better dynamic range, more pixels to meet the need to landscape and studio photographers, uncompressed HDMI output and may be 16 bit color depth, who knows.
Folks, please comment what would ytou like to see in new camera. Thank you,
