Bear in mind this is an "interview" with Canon Professional Network, so just treat it as an advertisement really.
Still, he does mention (and more importantly, they do print)
But of course, this is in JPEG only...

From my testing, and looking at the images I produced, I think that [ISO] 25,600 is about the same in terms of noise performance as the EOS-1D Mark IV is when shooting around 4,000 to 5,000 ISO. As such, I’d be totally happy to shoot at ISO 25,600 on the EOS-1D X without having to worry about it. Even if I had to go higher, I wouldn’t see it is a major problem because the files really are that good.
