The SP DLC has already been leaked. Do a search.
The SP DLC's main character is Bill along with his partner Frank. The story is based around how Bill's Town came to be, and the events that lead up to his break-up with Frank. Along your journey, you must find and collect as many magazines as possible during the outbreak. This ultimately answers the question about his collection of magazines and where they came from.
There are rumors that the main weapons you use are the Bow (which Bill is proficient with), his Nepalese machete, and of course the nail bombs he invented. Hopefully his shotgun (my favorite weapon) makes an appearance.
Also rumored is you play Frank in a few scenarios and also part of the gameplay revolves around setting up a "tower defense" around Bill's town setting traps and nail bombs with hordes and hordes of infected attacking Bill's Town.
Sounds like a controversial DLC but could lead to interesting gameplay.
I was just trolling for shts and giggles.
I thought the hunt to collect magazines would be a dead giveaway.
