What’s next? (updated list of Photokina 2018 rumors)

Here is an updated list of all upcoming/rumored cameras and lenses that will be announced for the 2018 Photokina show:

New Ricoh GR camera
Fuji GFX 50R
Fuji GFX 100s + new GF lenses (not expected for Photokina)
GoPro Hero7 Black camera
Rumored Leica cameras and lenses
Rumored Nikon cameras and lenses (Nikon still has another event on September 25th, but I don't think they will announce anything major)
New Irix product
Canon may announce a new camcorder
Three Sigma cinema lenses (updated: announced today)
Two new Sigma lenses (one is rumored to be 70-200mm f/2.8)
Zeiss mirrorless digital camera
Zeiss Otus 100mm f/1.4 lens
Zeiss Batis 40mm f/2 CF FE lens
Sony is way behind on updating their A-mount offering and APS-C mirrorless product. A new Sony A7s Mark III and Sony a6700 cameras are a possibility as well as some new E-mount mirrorless lenses (200-600mm, 24mm f/1.4 GM) but I have not received any reliable information yet.
Olympus may announce a new special edition camera or a lens for their Micro Four Thirds 10 years anniversary (2008-2018) or for the company's 100 year anniversary that is coming next year (October 12th, 1919). A major Olympus announcement is expected in 2019. Olympus 12mm f/1.2 PRO lens is still a possibility, but I have not received any reliable information yet.
Panasonic already has a Photokina countdown but we still have no clue what they will announce - I am very skeptical of the questionable reports for a new Panasonic full frame mirrorless camera (it will definitely not have a Leica SL mount)
Profoto B10
Light is planning to release a 9-cameras smartphone
Affordable RED 8k camera

I don't think...

I don't think Samsung is coming back to produce mirrorless cameras as some reports suggest...
I don't think Samsung is producing full frame sensors for the questionable Panasonic full frame mirrorless camera...
I don't think Sony will announce a new a7000 and/or a new a7s3 cameras this week as some websites have suggested...
I don't think Zeiss will announce their Batis 40mm f/2 CF FE lens this week as some websites have suggested...
