The D7100 has better video, if you are planning on uncompressed recording.
Gosh, did they finally fix the "self oiling sensor" problem with the D600? You might want to ask how long the boxed D600 has been in the distribution pipeline, or on the shelf. (getting long shelf life on inventory is one of the down sides of supporting local business if you don't ask how long they've the particular camera in their establishment. That's not to say it can't happen on line. One should always confirm the MFR date on any expensive item.)
For me the major problem would be this:
The D600 still has a low-pass AA filter built in.
The D7100 does not have a low-pass AA filter.
Taking out that filter (not user do-able) is the new development that are giving camera's MUCH sharper images (many people are misconstruing this as Higher resolution...NOT!) Low Pass filtering (AA) has always de-sharpened the captured image slightly, which then leads to the exercise of setting sharpening in camera, or in post processing.
Nikon took the AA filter out of the D7100 for a particular reason. Along with whatever other advances, the removal of that filter kicked the image sharpness OOC up considerably. It was NOT an increase of sharpness in the sensor. It was a removal of an impediment that have been in digital DSLR camera's for quite some time.
Nikon also took a similar course when the D800 came out, after which they neutralized the low-pass AA filter and introduced the D800E for sharper images. And more money for taking OUT a component, thereby reducing production cost in parts and labor.
But the price went UP! $300.00Olympus has been using weaker AA filters since the E-PL1 which produces visibly sharper images than the previous camera with the same sensor and process engine. They are still using that technique.
Sony, Pentax and others are tackling the low-pass filtering as a means of creating sharper images.
The D600 still has a relatively normal AA filter, if that can be considered "normal".
That and the history of the D600 is a deal killer for me.
Also there is a site that rates repairability of the D600. It ranks the D600 at a 2 out of 10 possible for repair ease.
