Nobody want to comment on that?
OK I will...
It's not a progression of bodies though... all he's doing is highlighting what anyone who knows anything already knows. Canon update their image processors more often than Nikon do... or DO they?
This just shows how little KR actually knows. They're not the same camera at all.
He states that the D4, D800 and D600 are essentially all the same, so just get a D600. Well.. what KR is clearly unaware of is that there are several versions of each Expeed3 chip. The D800 and D4 use the EI-158 which is optimised for speed in the D4, and 1080p, uncompressed 8bit video over HDMI and rolling shutter performance in the D800. The D600 uses the EL-175, which is optimised for the newer DDR3 memory on board.. but is actually a revamped Expeed 2 processor. The D600 he raves about is using last generation's image processor, the same as the D7000, albeit optimised for faster memory.

If you're gonna bore people with facts, he should at least get them right. All he's actually said there is that the 1DX is faster than the D4. Well.. we already know that Ken... thanks. The D800 is slow... yes.. we know this too... Oh.. and Nikon are sluggards when it comes to releasing new image processors. We know this too, and have done for 15 years.
Only Ken however, can weave all this into a fabricated story about all Nikon's being the same and stir up a hornet's nest on the interwebs... and just look at how many people have swallowed it!
He's pandering to the lowest common denominator who can't be arsed researching the facts, and don't know any better.
B&H probably have large Canon stocks they need to shift
Basically... he's a troll... stop feeding him.
