Looks like you are carrying a peeve from our disagreement on the 24-70 thread.
No one said that the 5D3 was not a good blend/ all round camera, I own one myself. But I still think they Milked me and you.
I'm not carrying a peeve. I do think we have a philosophical disagreement on both of these products.
It is clear that camera manufacturers (not just Canon) introduce products at elevated prices to take advantage of early adopters. This is true in many areas of commerce. The subsequent decline in price is a form of variable pricing, which increases profit by attracting buyers at different price levels at different times. Those who have an immediate need are willing to pay more. Those who don't have an immediate need are willing to wait and save some money. But there is nothing wrong with this. No doubt, the 5D3 has some extra introductory "load" in the pricing. It will eventually fall in price like most cameras do.
However, other than that introductory bump in price, I don't think we have any basis to say the 5D3 is overpriced for what it offers. It's not a fungible substitute for the D800, so why should it be the same price? It is likely that if Canon had to target the 5D3 for a lower selling price, then it would have been a lesser camera in some details, and then people would have complained that it should have been better. I can't prove that, but I think it stands to reason.
