I have an E-1 and E-3, the former now being a back-up or for when I need an unobtrusive and uncomplicated body. I still prefer the simplicity of the controls on the E-1, so maybe what we will see is an E-1a using the original dial controls/layout, with the E-3's Sensor, larger screen 'fixed' rather than articulated, employing the E-3's shutter and faster AF system.

This would not in my opinion, be a retrograde step design-wise, because the ergonomics of the E-1 (and that wonderful 7-14mm zoom) must have been one of the major reasons why people bought into the system. Indeed I have heard that a fair number of pro Canon and Nikon users purchased the Olly with just the 7-14mm zoom, because these two manufacturers weren't offering anything comparable (F4.o, 117 degrees and minimal distortion.) The fact that the prices of s/h E-1's remain high, would seem to indicate that this design still garners considerable respect.
