They can't do any better. It's their flagship.

More interesting is to discuss is WHY Nikon chose the sensor inside D5??
why not use the same type of sensor that Sony has in their cameras , 42Mp BSI and with bigger pixels and 20MP or a further development of 12Mp sensor with column ADC up to 20MP, if now 20MP is a holy grail for sport photo=12-14 pictures/sec.Both have excellent low and high iso DR

regarding choice of sensor Nikon can do lot better
Oh how wrong you are. Sony sensors can't keep up with the speed without dropping to 12 bit A/D conversion - and then the image quality does indeed suffer, especially at high(er) ISO speeds... So the writing was on the wall and I have repeatedly pointed out to guys expecting the Sony DR craze sensor to make an appearance in the D5 that they could well be wrong - well they were wrong for a simple reason: readout speed, the sensor of A7RII type takes 1/12th of a second to read, and then the sensor hasn't even be reset for the next photo, such a slow speed wouldn't have cut it in the D5.
Unfortunately this also means that all those who unlearned proper exposure to satisfy their unhealthy addiction to DR now need to deal with inconsistent performing cameras if they want to use the D5 beside for example the D810 - they need different shooting techniques (the one requires exact exposure, the other severe underexposure) and consequently widely differing post processing (which isn't helped by the cooked RAW files the D5 provides with it's white balance prescaling which now not only messes with the red and blue channel data but also the green channel)...

Whew! First independent technical facts on the 1Dx MKII. I am a specialized shooter. Previously ISO 6400 was my go to. Now it seems I can use ISO 12,800. My D5, if only at this ISO, is by a narrow margin, the best there is in FF. That's all I wanted but there are many other improvements over the D4s.
Nikon did say that the ISO 6400/12,800/25,600 range was what they had made their sensor for. I have my D800 (apparently it edges out the D810) for those Low ISO Hi DR shots. If I need more than 36mP (rare) I can stitch.
