If the specs are true, I would rather have this than the D800. Less diffraction issues.

A 24MP D600 will have no advantage over the D800 with respect to diffraction, actually in reality a slight disadvantage.

According to Thom Hogan with the D800 diffraction starts affecting the image at F8 and above. Maybe he is wrong, but from reading that it would seem with a 24mp sensor, it wouldn't impact unitil say F11 or higher, which is where I'm usually at with my landscape shooting for maximum depth of field.

Diffraction isn't a sensor issue, and it doesn't suddenly 'start affecting' - at some f-number diffraction takes over from aberration as the main limitation on resolution and the resolution falls from that point, usually between f/4 and f/8 depending on the lens. The pixel count doesn't affect where that point is at all. Nor does the resolution suddenly drop at some f-number according to pixel count and a higher pixel count camera will deliver more resolution at every f-number. So, having fewer pixels does not help with diffraction, all it does is reduce the resolution to the resolution you might have had a some smaller aperture with a lower pixel count camera.

+1 Lots of people have been complaining that higher megapixels will cause more noise, cause more diffraction, cause more motion blur bla bla bla.
