Either way it's going to sell like hotcakes.
To whom, exactly?
n00bs, students, parents?
Just because somebody buys doesn't mean they don't know what they're doing. A body is only one piece in a whole ecosystem. The GPS and Wifi might be nice to have integrated and you can complain all you want about the specs but it's not really that bad. There's a couple things that would of been nice to have but I'm sure this camera will take some great pictures.
And that's it in a nutshell!
As an impartial observer, I'm wondering just who are the people doing most of the complaining?
5D MkIII users, I don't really understand those users bitching. After all they are definitely not the target buyers for this camera? Maybe they are annoyed about the built in WiFi and GPS, not being on the MkIII?
Is it current 7D users, disappointed that this isn't the 7D2 they were hoping/expecting?
Is it current 5DMkII users who can't afford a MkIII? They may well have some legitimate cause to comment negatively.
Or are a large number Nikon "trolls", always happy to have a go at Canon?
The fact remains that the people likely to use this camera will neither be pros or semi-pros, and it ought to be accepted that this camera is not for them. They are are, of course, perfectly able to express an opinion re the shortcomings regarding Canon's pricing and design philosphy and the debate is all the more interesting for that.
However, to damn a camera on the basis of it's perceived lack of, or perceived poor features, is a bit premature since nobody has yet had their hands an one to write a review.
