I know this may be a stretch but how likely would it be for the bodies that Scott tested to not be like the bodies that will be released? I forget the key words that were used something like AS Tested...how likely Canon could/would give him a couple of bodies that have cleaner out put than the ones that come off the production line?
In fact the preproduction versions output is not normally not as good as the final production versions. They will keep playing with the code until the last possible minute, which is why a 'first' version is often FW 1.+.
A firmware update! Inconceivable! Inconceivable! This has never happened before!
EOS-1D X Firmware Version 2.0.3
EOS 5D Mark III Firmware Version 1.2.3
EOS 6D Firmware Version 1.1.4
EOS 7D Firmware Version 2.0.5
EOS 60D/60Da Firmware Version 1.1.1

EOS REBEL T3 / EOS 1100D Firmware Version 1.0.5
oh wait.... it has happened.... and this leads us to a more important question.... how come there hasn't been an update for the 70D post-release?
