RF Mount in Cinema EOS

I've been seeing a lot of rumors lately addressing a CX00 version camera being announced with an RF mount. From my understanding, all RF mount lenses are focus by wire. That, at least to me, kills any hope it would have of working on a larger budget set. Suer dpaf, or whatever the next iteration of it is may be incredible, but unless my 1st AC can hit the marks over and over again, I don't see how it will be implemented.

What are the thoughts around that? How could this be worked around for RF lenses? Am I totally wrong with them all being focus by wire?
