Here are a number of places you can find news and annotated games from the ongoing FIDE World Chess Championship. I have made them all open up in new pages so that you can easily compare what they say about various games or view pictures side by side with analysis.
An excellent Spanish-language site with annotated games and reports after each round. They have a tradition of providing excellent notes, like these by IM Hectre Leyva on Round 4 match-up Topalov-Adams.

Light annotations and predictions from the GM and sister to participant Judit. She does not risk many long variations, but her notes are useful.
The official site of the tournament includes recent pictures and commentaries by the ubiquitous Nigel Short.
Internet Chess Club (ICC)
If you are not a member, there is no better time to try the seven day trial. Personally, I don't play much online but I feel I've gotten more than my money's worth out of their championship coverage (though some of the kibitzing is offensive and should be monitored).
Besides their wonderful live shows they offer round-by-round wrap-ups and will likely have some individually commented games. I recommend combining coverage on the ICC with ChessFM for the best live effect.
If you bought Fritz, Shredder, or another ChessBase program in the past year, chances are you are already a free subscriber to this site. Otherwise, there seems no better time to sign up for their free 30-day trial! Word is that they have some excellent GM commentary by Yasser Seirawan and my favorite Andrew Martin.
The Argentinian national newspaper has some surprisingly good daily coverage of the tournament plus additional reports and commentaries. And it is open access--no annoying registration required. You will find the most articles by simply using the "buscar" ("to search") button and entering "ajedrez" (chess in Spanish). You can also navigate to the daily report (if it is not lined off the main page) via secciones (sections)>deportes (sports)> ajedrez.
El Diario de la Republica
The local San Luis newspaper requires a very annoying and discouraging registration but the "suplemento especial" devoted to the championship is worth seeing. It is usually linked off the main page--I think the championship will be the biggest thing in town for the duration--and contains a game of the day with some commentary plus articles and photos that give a lot of local color. The pictures do add something--including one showing Topalov signing autographs for adoring fans which I have not seen elsewhere.
The Chess Chronicle (subscription)
As far as I know, they have not yet come out with annotated games. But I expect this to be one of the most complete presentations, to judge by some of their sample issues available online, including the most recent free issue with player biographies.
I will add any others I come across or which readers recommend.
