So we know now that the E-M1 is not the E-M5's successor. That's partly a function of the design (seems to be scaled up) but mainly the drastic increase in price - the E-M5 came out at $1k for body only, while the E-M1 is supposed to be $1500. Based on past history, it seems like Olympus is going to need an E-M5 successor within the next 6-7 months or so. The E-M5 will be two years old next April. Moreover, E-M5 prices have been slipping and I imagine sales will drop off substantially due to higher-end customers opting for the E-M1 starting in a few weeks. The way I see it, the E-M5 successor (let's call it E-M6) needs to walk a fine line between offering meaningful improvements over the E-M5, and not undermining the 'pro' E-M1. A few things are probably givens - WiFi and focus-peaking are the latest feature-du-jour. But others I'm not as sure about. Does the E-M6 get a VF4-derived viewfinder? Will it get a new control layout (the E-P5 and E-M1 both seem to indicate Olympus is still happy to move things about)? Most importantly, does it get the E-M1's sensor, or a lesser derivative (potentially one without PDAF)? Thoughts?
