Aren't there modern sensors that have electronic shutters? Why isn't this capability found on newer cameras?

  Electronic shutters don't work well with fast moving objects. You can get distortion. I think they don't read out the whole sensor at once.

    The global shutter on the Nikon 6MP CCD sensor was really global, not like the rolling electronic shutter on a CMOS sensor. You got an all-at-once still, the electronic equivalent of a leaf shutter; the current scanning versions are basically a "no moving parts" version of a traditional focal plane shutter.

  It's usually called a global shutter, and it adds complexity to the sensor design, because each pixel has a tiny amount of "memory" with a gate and capacitor to store charge into. There is a signal bus that simultaneously moves all the charges from the constantly exposing pixels into the storage areas, where the charge is no longer being increased by exposure, and can be read out asynchronously using a switching matrix and a bank of ADCs. This avoids the problem where the charges of the pixels you haven't read are still increasing through light exposure.
