To me, greedy isn't just wanting sales. "Greedy" is purposely charging a significant amount more for the product than its actual worth with no consideration for the customer.
And how do you determine what a product is "worth" ? We have something called a "market place" that does a very good job of determining what something is "worth". I put it to you this thing called a market place will sort it out, and neither the manufacturer nor the consumer has the power to dictate what the optimal market price for the item is.
Canon still makes their profit, while I believe I'm paying a fair price. Greed comes in when the profit exceeds what the consumer believes to be a fair price.
To me, all that indicates is that "the consumer" is not part of the target market for that product. If the consumer doesn't find the item to be worth the asking price, they may decline to purchase it. For example, I declined to purchase a medium format digital back. This doesn't necessarily mean that the manufacturer is "greedy", just that it isn't right for me. The same is true of the 5D Mark III (I already own a MkII)
That's how this thing called a "market place" works. If "the consumer" in aggregate, really believes the item to be overpriced, the item will fail to sell at that price and the seller will usually find that they get more revenue by lowering their price.
By the way, gradually lowering their price is one way to effectively do "price discrimination" -- that is, if 10 people are willing to pay 3500 and 10 people are willing to pay 3000, you want your revenue to be 65000, not 35000 (if you had a fixed price of 3500) or 60000.
If it were $3,000 I don't think I'd be complaining at all, actually. Maybe even $3,100. But $3,500? Very optimistic on Canon's part and it's taking advantage of the fact that some people don't actually care about price vs value
I don't understand why anyone is "complaining". No-one is forcing them to buy that or any other product, and it's not as though that is the only body that is compatible with Canon gear. There are a number of other very good camera bodies that will work with the accessories you have.
(usually this happens when someone has enough money that a $500 difference seems minuscule).
Again, if you're in the target market for this product, AND you're one of the people who needs to own the latest model almost immediately after its release, you probably have a few thousand dollars worth of equipment and really won't sweat $500.
I can afford it, so I'm not one of those people who's upset because they can't. I just care a lot about the value of what I'm getting.
Again, what is your measure of value ?
