Most consumer Nikon bodies, film and digital, had a flash sync speed of 1/60s, 1/90s and 1/125s while pro bodies had 1/250s. Pro and semi-pro bodies also have/had FP sync albeit with a reduced output.
The D700 had a mechanical shutter up to 1/250, faster than than and the speed is actually the CCD sensor turning cycling on and off. (Edited to correct the model number.0
Remember a flash image is actually two exposures: one the ambient light, the second the actual flash burst. Under most circumstances 1/60s will suffice. Remember, the flash burst is relatively short duration, like 1/1000s, depending on flash to subject distance, ambient lighting, etc. FP sync pulses the flash to match the first and second shutters to cover the narrow of slit exposing the image recording plane (film or electronic sensor).
The D600 is set up as an entry level FX DSLR body at $2100 (appx). The D100 ten years ago was, I believe $1500 as an entry level DX body. It will have a feature set below the upper D800 to deliver it at a reduced price point. Not too long ago, most SLRs did not have a DOF Preview button, only higher end bodies had this.
I think Nikon made the right call in having the flash set to 1/200s...which is appoximately 2/3 stop difference between 1/125s and 1/250. When was the last time you need to have a faster flash sync?
Don't forget the D600 base ISO is 100, one stop less sensitive than ISO 200.
