Some of the cameras were produced with a mis-programmed left focus sensor. Checked mine and it’s fine. You can find more info here on Thom Hogan’s site:

Don’t worry Shannon, any remorse will fade once you see the unbelievable resolution of your new camera. It still amazes me every time I use it.
Regarding the D600, yes, it’ll be almost as great. 24mp, prolly smaller & lighter (w/o 100% viewfinder), less robust body, no focus screw so no autofocus with non AFS lenses, and a 10mp DX mode. Available to buy sometime in early 2013. Excellent!
