Certainly GPS and wireless will be added, and will have many users as well as detractors.


Personally, I'd like to have wireless control of my camera rather than the 6 ft usb tether (yes, I have a long usb to networkcablethat only works at 10mb/sec). I use my camera in a studio tethered to a pc for precise manual control of focus, aperture, ISO, shutter speed, etc to get just the image I want the first time. I haven't bought one of the $800 wireless grips, they would not pay for themselves in my case.


I could certainly imagine bird and wildlife photographers wanting wireless control of their camera from a laptop far enough away so they are not in danger, or so that they do not disturb the subject.


I'd use gps as well, it sounds like a good way to help organize images by location wather than typinng it into the metadata on import.
