i'm sure its a temporary issue that will be taken care of by canon relatively quickly. i am pretty sure the d2x had a similar issue at it's release? just slack QC really...
but...
you should see the canon fan boys going at it on dpreview!!!!
it's hillarious, they accused one pro who has two bodies (and he wants to get rid of them, because of this particular issue) of being a flamer... and get this, not a nikon fan boy flaming the mkIII, but a 5D fanboy flaming the mk III
those dpreview canon heads are caaaaraaaaazy! it was quite the laugh!
heres the thread:

i thought it was entertaining...
edit: i might add that the issue that a lot of canon-ites are citing as the major shortcoming with the mk III is the lcd screen resolution. it was mentioned somewhere else on here that although it is .5" bigger than a d200 screen, it has the same resolution. i suspect that canon will revise this, but it does seem odd that this wasnt picked up pre production?
