Today a third source confirmed the rumors about a new super high end Olympus camera coming in 2019:
I have also heard about Olympus coming out with a “super high end” camera next year. I was not told that it would be teased at Photokina, but I was told that the E-M1 MkII would be surpassed by a new camera. No further details were provided.
I repeat that as far as I heard this is not the E-m1III or E-M5III but a new line of cameras. This sounds really exciting! I hope trusted sources can share us some solid details soon…
