There have been no leaks so far about the new GH6 and OM cameras. I guess that’s because both cameras will not be fully released tomorrow. Expect more of a simple “pre announcement” press release.
UPDATE: I have been told that at least in OM Digital case we will get only a small hint of info about the new OM camera.
If you happen to know more about both cameras drop me a message at email@example.com!
