A couple of lens rumors today!
1) Olympus will launch a new roadmap tomorrow at 14:00 London time. This includes the already known 150-400mm lens, a new 12-45mm f/4.0 lens and new tele lenses.
2) Sony will announce a new fast wide angle GM lens in very early 2020
No info yet about their new cameras. I am pretty sure tough that Sony will give us the A7sIII and A7IV in 2020 and Olympus the new E-M1III.
UPDATE: Announced today! this is the newly announced roadmap:
