List of upcoming/rumored mirrorless cameras

Here is what to expect from the major camera manufacturers in the next few weeks/months:

Panasonic X200 compact camera. New MFT camera is also a possibility: few weeks ago the Japanese website Nikkan reported that Panasonic will introduce a new 6K 30fps capable camera before the end of their 2016 fiscal year (March 31st, 2017).
Two new Olympus cameras: E-PL8 and TG-Tracker.
After the X-Pro2, the next big release from Fuji will most likely be the X-T2, I expect the announcement before the Photokina show in September.
Canon is rumored to announce new mirrorless cameras and at least one premium compact camera.
Leica is rumored to announce a new Leica M-D Typ 262 digital rangefinder without a LCD screen. A M 240 replacement is expected at Photokina.
Nikon may announce their new larger sensor mirroless camera later this year.
Ricoh is also rumored to announce a new mirrorless system.
