Well, for the last 25 years or so, most film cameras also made use of multi-function dials.
I think what you should really be asking is, "are any m43 layed out like a primitive all manual camera?"
I guess I bought a Canon EOS 650 when it first came out in the 80's and thought of it as a "real camera," even though it used an ergomically brilliant multi-function dial.
I have enjoyed shooting many basic quality all manual cameras from rangefinders to mechanical SLRs, but really, with good ergonomics, a more sophisticated camera can still be a joy to use. The mechanical feel of the Oly E-Px series of cameras feels very "real" to me, the lower end ones with more screan menu searching less so. Don't know what you're looking for, but maybe you should try to handle an Olympus E-P3 or E-P5 and see what you think. I'm still shooting an E-P1 and shoot it just like I would most film cameras -- aperture priority mode, thumb wheel is dedicated to aperture setting, add EV correction when needed. No going through menus, nothing. Physical wheels and buttons.
Good luck deciding what you want!
