D4X with a 75 megapixel sensor?
If you took the pixel size for the V2, and applied that size to the FX size dimensions of 35.9mm x 24.0 mm, you get a sensor measuring 10,560 x 7,070 or around 75 megapixels.
The D800 worked out to a similar result if you took the pixels of the D7000 and applied them to the FX sensor. It seems to reason that Nikon is perfectly capable of delivering a 75 megapixel camera. The issue is probably processing speed and might come with a 2-4 fps frame rate.
For a landscape photographer - or someone who wants maximum resolution - such a camera could be attractive. File sizes would be large - double the size of the D800 files or around 150 MB uncompressed. While a little slower, such a file size could be handled with new processors and a larger buffer. Computers would have no problem handling the large file size even though it might be a little slower.
Obviously this is a high end camera with advanced features. The XQD memory is specifically for this kind of application and supports the faster write speeds that would be needed. But it would be a worthy part of the D4 lineup.

Shoot a frame with 3-4 models in it full length and then go do skin and eye retouching. That's why. I'd take 100MP if it was offered.

Medium format has been here for years... In fact, there have been 80MP pixel backs for years. And doing it with 16bit RAW data files.
I very nearly decided to dump my Nikon gear, buy a Phase One with the IQ80 80MP back and give up sports photography. Would have been an even trade in terms of money invested.
I see no need for XQD for this. Maybe nice, but certainly a luxury.

DigLloyd would certainly be all over it! And as a halo product, I think this is needed, not everything Nikon does has to stand on it's own as a high-volume product.
Pair up the 58mm f/1.4 with it too.
I think there is an interesting backstory/conundrum going on in Nikon's current camera sensors:
- The Aptina sensors in the Nikon 1 kills every other competitor and even all other Nikon cameras on the market for speed of getting data off the sensor (it's not even close);
- The ISO-less Sony sensor's kill everything else on dynamic range and recoverable non-noisy, non-banding shadow recovery, but they seem to be speed limited;
- Nikon's own line of D3S/D4 low light high speed sensors are very good as well.
- all of the above need to support on-sensor PDAF go-forward. Is the Nikon 1 tech for high-speed-sensors scalable in this regard to DX and maybe even FX and can we get on-sensor PDAF that is good enough? This may be what is taking Nikon some time to assemble.
In a best of both worlds scenario a 54mp 10fps D4X would find a bigger market, but I'm probably just wish-listing given the current state of tech. Meanwhile regardless of fps, a high mp monster D4X from Nikon would be welcome for the highest-end pro fashion, landscape, studio, etc. shooters.
