Finally I can give you good news: Highly trusted sources confirmed Olympus new super high end camera is a real thing and it will be on market by early 2019. They confirmed the new camera will outperform the E-M1II. They also said Olympus is unlikely to tease this camera at Photokina.
We have no specs yet but there are three possibilities:
1) This is the new E-M5III. But I wonder if Olympus would relley make this camera outperform the E-m1II (it would kill the camera sales)
2) This is a new kind of Micro Four Thirds camera. Maybe more video oriented.
3) This is a camera with new sensor format
I hope sources can tell me soon which of the three options it is…
