I can say it honestly depends on what the developer and its publisher does. They will give pre-order goods out through amazon, but only if it generates enough interest. Like let's say that this is Halo, CoD, or Gears- then yes your more likely to get pre-order goodies. Because Blockbuster brands sell like liquid.
However each store, online or off will each give different pre-order stuff, unless its a Deluxe PC copy where you'd likley get it all w/DL or physical disc.
Oh and its coming in March 2013 at the time of the post.
Gamestop offers an EXCLUSIVE zombie herd mode, which im pretty sure is the only multiplayer in the game. On top of the herd mode they are also giving out a weapons pack, not sure if it's the same one as amazon, but I don't really care to be honest... I picked gamestop because of the herd mode bonus.
