The actual cost for Canon to build this camera is $2400.
This is very, very hard to believe.
By Christmas 2013, Canon will be selling the 5DIII for $2499.
Obviously, the 5DIII cannot sell for $2499 if its costs $2400 to build.
And yet, it will sell for that much. Mark my words.
I personally think the $2400 value is the cost that they sell to retailers or distributors. The actual cost to make the product will be far less. This isn't a game console where they make money back on the games. They make a big chunk on the hardware itself.
If it is the cost to actually make the product, then it will include the R&D costs and the production line. Something that no doubt will decrease rapidly as the camera sells.
I personally don't think they can go on long selling it at the price it is. A $500 drop will come soon I think, especially with cheaper Nikon rival SLRs.
