After Canon has learned from 5d3/d800 that obviously few people are willing to switch to the competition, their only thought seems to be to upsell to the 5d3, and that's why they removed a lot of firmware features that could be implemented for zero cost....
Well, it is a business, not a photographers' aid society. Photographers upsell too, as do countless other businesses, not just Canon. I doubt that anything can be implemented in a camera for truly "zero" cost. Any feature has to be be designed, built (or coded), tested and evaluated, refined, tested and evaluated again, added to the production process, added to the product manual, added to the product marketing, supported for the life of the product, etc. Add up the worker-hours needed to do that, the opportunity cost of having them diverted from other work, the cost of the facilities where everything gets done, and the wages and benefits of all of the people who do it, and there is nothing in a camera that truly has zero cost.
