If you're looking for something to do while waiting for the WD, check out the comics. They are fast approaching issue 100 and getting back to some bigtime action in the storyline after a pretty long hiatus.
I'm also reading World War Z. It's written somewhat documentary style while a bunch of different interviews telling the big picture story. Took me a while to get used to the format, but they can cover a lot more ground that way. All kinds of pretty interesting info on how "Zack" (Code word for the undead) was able to take over most of the world and how it spread so fast. In this version you do have to get infected like a virus - those who die in other ways don't come back.
The book shows why the military was mostly ineffective, what happened in many different countries, how people survived, and the changed world post apocalypse. A lot of the stuff we have talked about in this thread is in there, like going back to castles/walls, using makeshift swords/sheilds, using the colder weather to freeze Zack. Its also an interesting perspective on how the living react - how they can be just as dangerous or more than the undead. They cover all the misinformation that gets people killed and something called a Quisling - people who snap and start acting like Zombies, further driving misinformation for the survivors. Good stuff.
My only complaint is that there really isn't a main character to follow yet outside of the interviewer - just a lot of seperate stories from survivors, some more interesting than others.
