I think the GPS is a useless addon, provided you have a smartphone + an inexpensive appli like GPS4cam. It offers IMO the same benefits of an integrated GPS. I'd rather like Canon focus on photographic specs rather than these useless peripheral specs, that cost a lot for a very weak added value. The smartphones HAVE a GPS, we have a smartphone always with us, bar.
About the WIFI, this could be differerent, but there is too a dedicated grip... So ? I really do prefer high iso performances for less MP, weather sealing, and a lower price... I'm maybe old fashioned ?
Disagree
I do not belive that an in camera GPS is going to add a lot of cost to the camera. I'd rather have it in camera than pulling out the smart phone, capture the GPS coordinates, identify the image to add the coordinates in post process sounds like too much of a hassle. I subscribe to the idea of have everything but give the users the option to turn them on/off.

please correct me if I'm wrong on this one, but the camera will have a 'true' GPS, meaning a GPS that will function on its own, whereas a smart phone only has the aGPS meaning assisted GPS where it will need a Wifi connection or 3G connection to be able to obtain its position. + the extra hassle of having to connect it to the phone and all that annoying stuff that won't work properly anyway, no I'm not a fan of having to rely on my phone and in this case some home cooked app too much.
The problem with GPS without A-GPS is how long a cold start takes. The transfer rate from a satellite is extremely slow, and even though it's only a couple kB it can take quite a while, and only then can it attempt to acquire a lock. A-GPS has the benefits of being able to download that data from a faster source, and having a rough estimate of current location so it can determine where it is way faster.
Cold start may take longer but I'd rather have it in camera than another device that I have to pull out and go through the hassle of tagging them in PP. At some point someone needs to take the initiative of including them in Semi Pro DLSR's and that's where further progress can be made with faster locking on to the coordinates can be achieved. A good example is Canon 600 EX-RT speedlite ... yes there are some AF issues, but unless the RT was not integrated by one of the big names, there would not have been much progress in this area.
I subscribe to the idea of useful new technologies being integrated into products that can benefit people ... at the moment I see WiFi and GPS as very useful features for a lot of people, especially if the user has the option to turn them off.
I agree completely, the more features the better. I would just prefer that features that may impact reliability be deployed with extreme caution to "single digit" bodies. I don't think WiFi of GPS would impact reliability in any appreciable manner (excepting the occasional "battery died because I forgot to turn GPS/WiFi off"), things like swivel screens still worry me though.
Perhaps my fear is unfounded; I never had any problems with my 60D, nor did I ever hear of anyone else having problems. But I also literally never used it, and haven't missed it one bit on the 5D3.
I used the swivel screen a lot on my 60D, but I sold it last week to one of my colleauges as I was hardly using it ever since I bought the 5D MK III (last August) and TBH, I did not miss the swivel screen ... maybe I am just in awe of my "first full frame" DSLR. But I do see swivel screen's usefulness for people like me who are nearing 50 (or above) and having difficult time getting up quickly after crouching/lying down on the floor for a nice shot of a flower or some macro shot etc

... so let's settle this disagreement into what we can agree on: Swivel screen for old farts like me and no swivel screen for strapping young lads like yourself

... I have taken the liberty of assuming you are a young lad, but no disrespect intended ... I meant it as a compliment.
