And just think of the possibilities! Automatic in-camera AFMA? Somebody will write a script for that! Want to do an automatic sunrise picture sequence? Write a script that starts shooting when the light arrives! Want the two wheels to do aperture and ISO instead of exposure time and aperture? Just change the function that's called for the wheels! All buttons would be mappable to any script. You'd be really free to let your camera do whatever you want. If you don't have the programming experience, odds are, somebody else with the same requirements will, or you can find and pay somebody to do whatever you need. The internet would be full of scripts, and here on TDP there'd be a well-chosen selection of them :-)
