3rd Pic = Poor quality game rendering processing power which means it is not a current generation console. Treyarch would have created a full quality, long distance rendering screenshot if they'd really wanted to release a screenie of zombies. It's also too open.
4th Pic = what does this have to do with zombies? It's a previously released pic, unsure if it's been edited or not though.
