The sensor is the most expensive part, which is 600. All the mechanics together (in a semi-pro camera) cost around 500. The circuit boards cost around 400 (in a semi-pro camera) and the AF system is a part of it. Plus all that is considerably cheaper in a non-retail situation when they are assembling these camera at a factory. Maybe 60, maybe 40, maybe 25, I don't know.
What you have given me is not evidence - it seems like a list of suppositions. Where are you get your information to say "The sensor is the most expensive part, which is 600. All the mechanics together (in a semi-pro camera) cost around 500"? Canon make their own sensors so how do you know?
How do you know they use the same circuit boards?
What about the AF sub assembly? Programming the system for the camera?
If you have genuine knowledge that is one thing. If you are assuming based on other areas then it is less secure.
So far your number account for 1500 out of 2,000. Add the body (including machining the mount) and other parts, add packaging and distribution and it looks like your claims of room to throw more things in for free are total fantasy
