So let's dream. I want a new, global shutter sensor. This would eliminate the need of the shutter... 1/32.000s.. Wide open in daylight without ND.
Combine it with a proper flash sync speed for freezing actions and i'm all sold.
If they could add a good video eith flat profile aww man!
(Or the wildest guess: layered sensor. I'm fine with APSC dept of field, but a 24-28 mpx true resolution layered sensor would be a beast in terms of DR and high ISO)
