Well I think People have to look at a percentage of failures, for bodies sold, and reliability.
I see 40D problems only a very few, but how many bodies have they sold, Thousands all ready, I bet, wonder how many MK3 have been sold since it's release, I think it is good people report these things, it gives people an idea's of reliability, something that is very important.
Well if you think they started at 501*** and are now on 535*** that would suggest around 34,000

and prob re-badge with new S/N after upgrade, who knows.
