Before i start, this is NOT about the sensor-file size- FPS and so on. I only tried it for a few minutes in a shop and can't say anything about that, what i can say something about the weight-size and price. (what Tony talks about too)
First off. I'm almost 7 feet tall and about 270 pounds. I currently use a Canon 1Dx (mrk 1) and the grip on it is actually a bit to small for me. (See pic) For me this is the best solution. I HATE using "normal" size DSLR's because they are just too small. I have a 70D and i feel like i'm about to drop it every time i hold it. The smaller cameras from any manufacture is just not possible for me to use.

Price: Let's say you're starting from scratch and need a body plus a 70-200 lens (and yes you do need a grip if you shoot vertically a lot. and you do that in sport)
Canon 1Dx mrk ll 49.995,- dkk
Canon 70-200 ll 16.995,- dkk
Total: 66.990,- dkk
Sony a9 40.995,- dkk
Sony 70-200 (E) 22.995,- dkk
Sony grip + battery 2.995,- + 700,- dkk
Total: 67.685,- dkk
So here in Denmark it's the same and even if you leave the grip out, it's so close it almost doesn't matter.
Weight: Again. I'm a big dude so it's not a problem for me (but i am getting older) If you have the grip for the Sony you save about 400 g.
I heard T&C talk about the amount of shots you can get from the a9 in their previous video and good for that. Sony was WAY of on previous cameras with FPS on one battery. Without anything mechanical moving it should be able to do well. I have the same battery's i got with that camera. I have taken good care of them and calibrated them when the charger told me to. They were bought on May 10 2013 and both still kick ass

Noise: Yeah.... But at least my Canon is not as loud as a Nikon
Video: Don't use it, don't care
I know i sound like a fanboy and i guess i am. Mostly because i can't afford to switch brans, but also because the 1Dx has been with me through mud, rain, frost and tropical heat and just kept shooting. I wanna see how well the a9 does in winter.
I want to thank Tony for always making sure he tries to cover everything in video, even though it's impossible to do and this is not a bashing of him or the video. Just wanted to point out a few things from my part of the world and my POV.
