David, Re the Wikipedia article on autofocus to which you referred: Per DP Review, the new Olympus E-M1 (which I think is on your short list to replace the venerable E-3) comes with two flavors of autofocus built in: Contrast Detect (Sensor) and Phase Detect Here are the details: http://www.dpreview.com/previews/olympus-om-d-e-m1/7 Autofocus seems to be a mature technology (or -ies) and is influencing many areas of camera design, which may be obvious to some but it wasn't obvious to me.
