Aargh... missed the link. Anyway, Canon is not strictly using a sequential numbering by date system - EOS 40D is numbered before EOS 30D...

Probably a "next available" scheme where they don't burn an ID when a product gets cancelled, but instead reuse it for the next product in development.

Guys, why did you forgot the
stress and endurance Small | Large
tests? I am talking about the EOS pro equipment.

They must have:
- components tests (remember the 100k shutter guarantee? That means at least 120k successful on some 98% of all tested ones).
- weather & environment tests...
- Body and main circuits imperfections (remember the stupid 5Dm3 light leaks).

When are all those tests taking place?

One would hope continuously, every time a component changes significantly.  If the shutter doesn't change (for example) and the body mount hole area doesn't change, there's no need to test that aspect of the hardware again (other than as part of the general user testing).  When a part does change, you would expect several rounds of stress testing.

A lot of these tests are done as component tests (i.e. unit tests in the S/W world).  As soon as the tooling is done, they start running the tests on those items, but remember that many of the components are off-the-shelf (OTS) as in existing components from other camera models.  The testing of the final, completed camera body would begin as soon as the first fully-assembled body rolls off the line.  Some would go out for field testing (World Cup?), others would go into the automated testing with robots pushing the shutter 100,000+ times, weather simulation rooms, impact tests, etc.  The automated testing takes much less time that you'd think with the robotics and specialized testing labs.
