But when you end up shooting at ISO 6400 there will be a price to pay in image quality. I would rather use an M43 rig combo of 300f4 and 1.4x teleconverter, 420mm f5.6, which is the FF equivalent of 840mm f5.6.

kind of

How, kind of? At 840mm you have a very small DOF and will often need about F5.6 - at least that is what I find.

so about the same dof as the canon 800mm/11 used with a 35mm sensor

Not sharp, poor contrast, etc.

are you talking about the 300mm/4 and 1.4 x tc? because it can't be about the unreleased lens from canon

Certainly not the 300, as compared to, though. I read one prerelease review of the cannon. Apparently that type of lens has a tendency for poor contrast and light gathering.

and here i was thinking they hadn't even been officially announced yet, pre release review of just a rumour....i'm impressed

Prerelease preview of a rumor. Awesome.
