But would anyone crop boobs?

That's what caught my eye, too, and as someone who uses ISO 102400 on my 5DIII all the time, I might have to sell all of my Canon gear to get the D4S.  I think it will really help with my upcoming series - Coal Mines by Matchlight.  If I accidentally run into some methane, this might be my last post ;)

I thought you were doing A Bat's Eye View series

Canon is preparing the even smaller SL2 which will be mirrorless and full frame (tongue in cheek)

I would bet medium format shooters snicker at lowly FF shooters and the FF shooters resort to the same arguments APS-C shooters make.  :-)

I'm disappointed that the Nikon D4S is only 16.1MP.  I was hoping it would exceed the 1DX with 24MP and put pressure on Canon which would in turn put price pressure on the 1Dx to make it more affordable and certainly downward pressure on the 5D3 and 1D4.  Right now, it still looks like Nikon is still playing catch up.

"The overall signal to noise ratio of a sensor (SNR), observed at the scale of a single pixel, is dependent on P, the incident photon flux (photons per second in the area of a pixel), Qe, the quantum efficiency, t, the exposure time, D, the pixel dark current in electrons per second and N, the pixel read noise in electrons."

I don't see signal-to-noise ratio as a function of total area here although I would concede a larger sensor area make for a better photo in terms of composition and framing.  The exposure time would be a function of lens aperture so a larger aperture will improve SNR as well as pixel efficiency.  Newer, and presumably better, sensors would be better than older sensors at high ISO regardless of sensor size when you are talking about APS-C and larger.

First of all, I did say low ISO performance is comparable.  The OP was looking for better high ISO performance.  Ass for size matters, you are talking about TOTAL light on an equivalent age sensor.  The current generation sensor sensitivity is similar per square unit of area so if you compare a similar area on the FF sensor that is equivalent to an APS-C sensor, it would be very similar in performance.  When you account for TOTAL area, obviously the larger sensor captures more.  It's like saying 2 solar panels are better than 1 but the single panel could be equivalent to each of the two solar panels.  Now the lenses' focal plane for both sensors is identical so the same image on the area of the APS-C sensor on the FF is identical is it not?  Therefore, that area would be fairly similar in image content and IQ for same generation sensors.  In fact the pixel density on the APS-C may even help it along.  20.2MP in APS-C vs 22.1 in a FF.  10% more pixels in 60% more area for the FF. 

Regardless, I'd prefer an 80MP medium format camera but even that won't suit what many of us shoot.

I would have to disagree and my opinion is that the 70D sensor and capability is vastly superior to 5 year old APS-C technology in the 7D and 6 years in the 500D.  I switched from a 7D to a 70D because I do get much better high ISO performance. IMO, my 6400 performance with the 70D exceeds 3200 on the 7D and the AF is much faster.  Anything above 3200 on the 7D was, in my opinion, unusable. When working at low ISO, the older sensors hold their own.  All due respect to Neuro but when was the last time you shot anything less than an up-to-date 1D series?  For better low light performance without a new body, go with large aperture prime lenses?

I've used the a Yashica SLR film camera before getting a 500D then after 3 years, went for a 6D.  I won't go back to APS-C again after that.  The shots I get from an FF and an APS-C is too different.  Aside from that, high ISO capability for an FF is too amazing compared to APS-C.  For events, an FF is really a joy to have.

You are comparing a current camera with 3+ year old technology.  The ISO capability has no connection to full frame or APS-C, it's a function of sensor age.  The 70D would have given you as big a bump in ISO capability at nearly half the price and allow you to continue using your APS-C lenses.  I could compare a 5D classic with a 7D and conclude that APs-C is superior in many ways.

If you are satisfied with the shots you are currently framing with APS-C and want better ISO performance, consider the 70D which is a much less expensive option especially if you have APS-C lenses

Lenses / Re: f2.8 16-35mmL vs. f4 17-40mmL

I upgraded from the 17-40L to the 16-35L II and the extra stop comes in handy not to mention the more expensive lens has better IQ in my opinion.   I went with 17-40L initially until I could get the funds for 16-35L.  With my CPS membership, I was able to get loaners of both.  The 17-40L did an acceptable job of shooting landscapes and cityscapes and you may be perfectly happy with it but I needed the extra capabilty of the 16-35L for "light" reasons.

My advice is to skip both lenses and adapt a Nikon 14-24mm. Both Canon offerings are incredibly horrible.

Sensible if you want a Nikon body too.  You do realize the OP doesn't want to change bodies, right?

It is the 7D, just Prototype Base Zero not the new version.  Wait, scratch that, it's the breadboard 60D!

I got mine a month ago from B&H for $949.  Wait for a real sale if you can.

I travel with this when I want to go light on vacation, 10 lb capacity and 2.6lbs total including ball head.  When I am working, I take my Induro carbon composite CT014 with either the ball head from the traverse or the Induro 5 way panhead.
