Ehhhmmm... Why exactly do you want a "pro" camera? What are you looking for and what are your needs?
My "Pro" cameras now tend to be Leica Rs (as well as Pentax 6x7s), but they were tendentially used by portrait, nature and landscape photographers rather than, say, PJs, meaning typically much less wear & tear (and also much more suitied for my needs & interests).
I also use some definitely "non-Pro" cameras, but they do their particular job very well.
A "pro" camera is really what meets your needs, whatever they are....
