What you practically demand is that a modern DSLR runs on a software like the iOS7 and has at least 4-8" screen.
A camera manufacturer does not need to go that deep because it's a waste of time and resources to do things that already exist and which others do better anyway.
A good wireless communication with a mobile phone and a tablet / computer is all what is necessary for a modern camera, and rest is solved through the more powerful services and software that mobile phones and tablets are running on.
Seeing on a bigger screen if the picture is fine, tagging pictures, naming, cropping, editing, sharing to hundreds of services, emailing, etc. is much better done on a tablet than on any camera.
And it is more practical for a camera manufacturer to create awesome cameras instead of fiddling with software "solutions". Camera manufacturers must reclaim their DNA, or, ensuring no tablet or phone can duplicate their part of image taking job — taking awesome images using awesome lenses and sensors. And then, they can co-exist with tablets and phones by emphasising their strengths.
A mutual respect in things that one party does infinitely better yields in interdependence, not in substitution.
Like that, camera manufacturers have a much better prospect for the future. Create less junk, but more truly outstanding cameras and lenses, with great handling, enjoyable to use and built specifically for an image taking purpose.
