I use a Nikon D700 and it does everything I need it to do for my professional photography. I can't see replacing it for a very long time. It works perfectly with all my old Nikkor glass from the 70's and 80's so I don't see what all the fuss is about with the new retro Nikon. If my D700 breaks I will look at what's available at that time. Whatever is going on with cameras in the interim is just a distraction from creating photographic images.
