I think the price is very reasonable for 1DX. I haven't heard many complains for the price of 1DX. I only hear the complain for it delay.
Yes, given that the 1Ds3 was at $8000.. I agree. but then again, quite a lot of the people who had the 1dx on preorder.. cancelled once the 5d3 was available.. stating that the price was reasonable (compare to the 1dx) with quite a lot of 1dx features built in it.
