[1Dx has landed at my work and of course we threw it in our gear modeling table to take some quick shots of it before we prep it for rental. I saw that as an opportunity to photography my 5DmkIII next to it for a side-by-side shot of both cameras. The 1Dx feels slightly better than 1DmkIV. It actually makes the gripped 5DIII feel sloppy and unwieldy compared to it (note, compared to it. the 5DIII is actually the best feeling gripped body I've ever held and I've pretty much fondled our entire inventory). I can imagine myself holding this comfortably all day with a 400mm IS II attached and not become as fatigued as man-handling the heavier and chunkier D4. The shutter has a nice sounding clunk to it, like the satisfying sound of slamming the door of a mid 80's Porsche. Its loud, mechanical and would probably scare children within an earshot.
That looks so good! Can we get a rear shot by any chance

What are the two buttons for on the front? I assume one is DoF preview but what is the one next to it?
Hm... not that I would ever complain if I was fortunate enough to own the 1DX... BUUUUT... I just noticed that the M-Fn button on the vertical grip side of the 1DX is placed in a whole different location compare to the normal grip. That would bug me.
(But only because I don't own one. I'm sure if it was mine, I'd say it's perfectly placed.)
I didn't notice that, but from other pics I did notice that the multicontroller is the same on both sides, that does bug my on the 5Diii grip 
But won;t be able to afford the 1Dx anytime soon
