Photography Blog also interviewed Setsuya Kataoka and got a few more details from him.
When asked about sports “the OM-D E-M1 Mark II is more aimed at sports photographers who work a lot on their own who can support themselves, and like the portability of a smaller system.” Also this is not the same sensor in the Pen F and reads out twice as fast, which is pretty impressive.
The two newest lenses that offer 6.5 stops of stabilization are the 12-120mm and 300mm at the time. The rest offer 5/5.5 stops. You have to use a tripod to use the 50megapixel mode, which is similar to their other camera that offers the same technology.
