I feel a great respect for them to admitting it. Really!
I feel it more ethical, than hiding it in some marketing bullS___.
As an electronic engineer and programmer (from time to time) myself, I feel more confidence in Canon engineers, they were able to produce one good hardware equipment and use it for different purposes. That's lowering total costs of production and this is good for us - customers.
All guys spitting on Canon because of this - you should really rethink your business and world imagination. Truely.
First of all - do you work somewhere? Let's assume you don't run your own business but work on a monthly based payment. Do you have savings? If so, then you should shame! If you have savings, then it means, that you charged for your work more, than it really costed! Bad boys! If you run your business, even photography or cinema one - how much do you charge for your work? In such a case don't you like to say: "my work is worth this money"? What does it have common with costs you made?
Secondly - if you don't like this and you are still where you live, then you should move to other country, were market liberty is not on the level, allowing to demand for the product or service as much, as someone is willing to pay for it. This is not the product of the "first need". This is not bread, milk or electric current. This is equipment made to make money for those, who can. If you cannot afford it because your work is too weak or your customers won't pay enough then this is not equipment for you so stop whining.
Would I like it for my amateur work? Yes. Do I consider it? No. If I had customers willing repay for it in some time I would consider but as a tool but also would consider a competition.
Is it wrong they don't want to sell an upgrade to allow you shooting at 4k with 1Dx? Only market will punish them if this is the wrong decision.
Is it wrong they admitted this is the same equipment? No, and +1000 (points, not $) for them ;-)
That's my honest opinion.
