Makes me imagine a 5D 3.1 with a nicer sensor - 1 stop more DR , less banding / noise and maybe 30MP.
And keep everything else with it!
(Then the proper Big MP can still be a separate beast!)
-What exactly is wrong with the 5DmkIII sensor?
-The 5DmkIII already captures a comparable scene with about 2/3 stop brighter shadows than Nikon, so you already have the ~1 stop more DR from the get-go. Stop longing for technology that serves limited other purpose than an anticipated ranking from a "pay-for-score" service like DxO. The reality with broad DR is that most people use it to create (read:recover) a shot they could have taken in the first place if they learned how to properly read/adjust exposure.
-Same thing with more MP.. A survey of the some of the largest printing firms in the US indicates that poster size prints represent the smallest percentage of their output - so very few people are printing posters and therefore have little argument for high MP other than hoping to crop a shot they should have properly composed/captured in the field..
Too many 'photographers' today are waiting for a camera with 200mp, full sensor AF, and 204,800ISO so they don't have to do anything but point the camera in the general direction of their subject and then go home and crop/zoom the shot they should have taken in the field - that is not photography, that is surveillance...
