How many pictures does an Olympics photographer take?

There's soime great photos by Toronto Star photographer Steve Russel here, alogn with a little story about taking them.

And at the bottom, Steve tells viewers how many shots he's taken since arriving in London, and how many today.

I do not know what cameras he uses; Star photographers choose between Nikon and Canon, and I know they've got new Canon 1D-X bodies.
