I've actually been REALLY wondering that too. I have had limited internet access for the past week, but otherwise would've posted the EXACT SAME THING.
Countdown with Keith Olbermann has become my favorite news show lately too...and I had heard claims he has AS, but see no definitive place where he says he has it or anything "official."
I really do wonder. His show is great, I already watch it over others. If he does indeed have it, he's very lucky to be in a job where he won't get fired over it (never made that obvious for not-want-to-get-sued-for-discrimination reasons of course, usually hid under the "he/she wasn't a team player" BS, in most other industries). The Chairman of NBC has a grandson I believe who is on the spectrum, and so I'm sure that, if Olbermann indeed does have AS, the guy at the top would be proud to have someone on the spectrum starring in the prime time lineup.
