I'm hearing of spotting problems with Nikon D600. Does this problem exist on the D800?

I'm asking on behalf of someone I know that is looking for these products.

Added (1). From what I understand, Nikon has not specifically commented on this problem, but many users are reporting oil splatter on the sensor and excessive dust.
Here are some web reports:

This is the first I have heard such a thing

By the way what is spotting problems?

Are you talking about stuck pixels?

Are you talking about dust on the sensor?

You are going to have to be a little more specific.

The D600 sensor is rated number

As you can see from this link, the Nikon D800, D800e and D600 are very close in quality and performance.

In the arena of best performing camera sensors, the D800e is number one, D800 number two and D600 number 3. All other cameras fall behind those three cameras.

DSLR's are assembled in dust-free environments so don't expect dust to come from there. Oil is strictly measured as too much will render the electronic shutter sticky and become inaccurate. For oil and dust to reach the sensor, the shutter must be left open while there's no lens mounted on the camera. If that were the case, it's user-induced then.

I have shot through dust and fungi even during my film days and it never bothered my customers. With digital, I'm having less issues about dust especially with the built-in Shake Reduction system of recent Pentax dSLR models. The sensor shakes up at a fraction of a second each time the camera is powered on so dust fall off it before shooting.
