I guess it comes down to what they can do in a set retail price......this camera is clearly aimed and designed at retail price of around £3500 as were previous 5D models. At this price you get ONE DIGIC processor and this will always limit what the camera can do. With the 1DXII you get two DIGIC processors which opens up a lot more potential but at a cost of £5200 !!. I personally think the 5D4 spec is spot on for this price, but being a 1DXII owner it makes me a little disappointed about the bigger sensor and slightly improved funtionality in the 5D4 seeing as the development of these cameras was done in parallel. Canon WERE capable of making a camera that we all want which has all the best bits of the 1DXII, 5DSR and the new 5D4 but instead they chose not to....and chose to release 3 compromised cameras instead. I use the term compromised loosely as these are still 3 amazing cameras.
