Well since Tony decided to spoil the fun, I decided to take down the link.
But I actually have done some shooting with the mkIII in low light and it's so much better it's ridiculous.
The noise is not blotchy like the 7D and mkII. Neat video cleans it perfectly!
The sharpening in post works like a charm too. Only need about 2% to make details pop.
Hope everyone is having a great April Fools day and go prank someone!!!

We all like a good laugh Robert, and I certainly wasn't trying to dampen anyone's fun. But April fools jokes aside, I was thinking more of people wearing headphones. Listening to that high-pitched sudden sound could easily damage ear drums.

On a lighter note, I'm glad that you're having fun with the new Mark III. :)
