User blog comment:Callofduty4/Robert Bowling hangs out on Google+, reveals DLC info/@comment-3967954-20120323075933

lol at all the people expecting gun DLC. Not only would it potentially screw up the entire multiplayer, but it'd also be a pain in the arse for IW (having to make new models and textures, balancing the weapons perfectly, adding compatability for the attachments, ect.), and even then the immature side of the community would probably complain that the new weapons are either "OP" or "shit".
