Couldn't agree more but bear in mind that what we have at the moment (in the E-M1) is not dual focus. It is 2 distinct and completely independent focussing systems and the one chosen is based on the lens attached.

A number of technologies from the PD and CD worlds need to be combined together along with cross type on-sensor PD to give a step improvement in focussing.
