@RickWagner and @Tugela:
You guys are both thinking about things from a smartphone consumer standpoint. This isn't Blackberry vs. iPhone, or Horse-Drawn Carriages vs. Stem Powered Cars. We aren't talking about run of the mill consumer grade devices here...were talking about refined devices meant for a professional, or extreme hobbyist who might as well be a professional. It's why I brought up airplane cockpits in my prior post...people have talked about making airplane cockpits more modern for decades, however they are still built today primarily with individual dials and knobs and levers and switches and readouts (even the highly advanced Dreamliner). Why? Because it isn't some run of the mill consumer device meant to be easy...but potentially inefficient...and therefor accessible to a billion consumers. It's a system meant for professionals, who have the knowledge to use such a complex device, and the expectations that certain bits of functionality exist in certain ways and are accessible by certain means...because it's important, when push comes to shove, that these things work the way they always have. (In the case of an airplane, that could mean life or death for hundreds...in the case of a DSLR, it could mean getting the shot or not.)
Which goes back to my original comment:

Comments like this make me think people don't know how to use a DSLR. DSLRs are devices that you need to instantly change settings on. ... It's sad how smartphone mentality is invading every other area of our lives...in many cases, a touch screen is the primitive configuration device, and all the "archaic old buttons and dials" are actually the vastly superior and far more reliable means of controlling and configuring something like a DSLR (or, for that matter, a remote control, an airplane cockpit, or a nuclear launch facility, or pretty much anything where the behavior of a given doodad has to be EXACT, fixed in behavior and place, reliable, hardened against rough activity, instantaneous, and immune to things like software bugs, viruses, etc.)
Digging through menus is one thing...however, how often do you really do that? I do it periodically, however in the grand scheme of things, once I have my Canon cameras set up for how I use them, I don't spend a lot of time in the menu systems, or for that matter on the quick view screen (the grid that shows up on the back LCD, which shows the current state of your camera...exposure settings, white balance, AF mode, etc.) When I do find myself in them, I've never found the dials or set button to be an encumberance...I can fly through Canon's menu system without even thinking about it. Touch might offer an alternative means, but I truly don't think it would be any faster or better. Just different. And I'd probably keep doing things the same way I have been for years, since it's programmed and automatic...I don't have to think about it.
I use my camera for photography. In my photography, which primarily involves shooting action (the primary use case for a camera like the 7D II or 1D X, and in many cases even the 5D III), when I'm actually doing photography, I use the buttons and dials. I rarely even remove the camera from my face when I have a subject in view. I use nothing but what is visible in the viewfinder, and basic muscle and procedural memory, to completely reconfigure the camera as needed, from an exposure, white balance, metering, and AF standpoint, for the subject and lighting I'm photographing. THAT is my photography. THAT is what I do with a camera.
Digging around through menu systems, or poking around through the quick access screen, are things I do when I'm NOT actually doing photography. There are a couple other use cases where a touch screen has been useful...but in those cases, it wasn't a touch screen on the camera. When I do macro photography, especially of tiny plants, close to the ground, I often have my camera mounted underneath my tripod. I flip the center post of my Gitzo Mountaineer around, attach the camera upside down, and drop it down low to the ground where I can get photos of things like mushrooms or other interesting forest floor flora...from the perspective of being on the forest floor. Having tried on many occasions, I can readily tell you that the live view screen is usually inaccessible or at the very best very difficult to access. My solution? Plug the camera into my Surface Pro, tether it with Canon's utilities, and use a REAL touch screen, a large touch screen, on a high resolution, 1080p device, to see what my camera is pointing at, adjust composition and focus, etc. For macro photography, I'd much rather have Canon invest some time and money improving their software with more controls, potentially the ability to fully control the camera, including focus, remotely via a tablet and a touch UI like that. It's such a radically superior experience. I also do the same thing for landscape photography. Getting accurate focus with a 10.6" screen is so much easier than on a 3.2" screen. It's like having a large format view camera with a huge 8x10 ground glass screen on the back...it's amazing.
So, sure, touch can be useful. I've never said it couldn't be. I am just saying...it's NOT how a professional or an avid enthusiast uses a DSLR. A pro or an enthusiast uses a DSLR the way a DSLR was DESIGNED to be used...rapidly, eye to the viewfinder, fingers on dials and buttons that instantaneously do what I need them to do without ever having to pull the camera away from my face and go touching my way through any kind of UI. In my world, graphical UIs are the clunky, intrusive, and slow means of giving me access to settings. Dials and buttons, on the other hand, are the cutting edge, giving me instantaneous access to things that I often need to change on a moment's notice, and things I don't want to have to pull my eye away from the viewfinder...and likely lose my subject when I do...to accomplish. Give me more dials and buttons, and I'll always find a way to use them. Ask any serious or professional bird or wildlife photographer, sports photographer, probably most any action photographer, and they will likely tell you the same thing. Why would anyone want to pull the camera away from their face to fiddle with a UI when they are actually doing photography?
It's a nice to have. It's the glossy polish. It pretties things up and makes them feel more modern. I'm not denying any of this. What I'm saying is, a touch UI is far from an essential necessity on a DSLR,
particularly on a device meant for pros. (If we were talking about the EOS-M 3 or a Rebel, my stance would be 180 degrees on this.)
