Most Popular Online Game at the moment?

Is there any way to determine what is the most popular online game at the moment? I don't mean popular by how many registered players, but rather, by the number of active players on average on any given week or month?

If I were to guess I'd say it's World of Warcraft for PC, Halo 3 on Xbox Live. Most popular all-time might be Counter-Strike. But it's just a guess. Is there any way to get actual stats and such?

Please share your opinions and insight. Thanks.
