Olympus is working on long telephoto lenses, major announcement expected in May

During Photokina, Camerajabber interviewed Shigemi Sugimoto from Olympus. Here is the recap from 43addict:

Still 100% behind m43
The size and weight of m43 is easily distinguishable for Full Frame
Full frame vs m43 makes the whole size advantage an easier sell
Everyone is making a big deal about mount size, well m43’s mount is twice the size needed for the sensor
Olympus is working on long telephoto lenses
Olympus wants to further reduce the need for tripods
Using current technology the cameras and lenses would have to get bigger for better IS, but Olympus believes they will surpass the limitations
They will have a major announcement for Photokina 2019 in May next year.
