If the gun textures/etc are not included in the base content on the disc and is contained within the DLC only, I don't see how the gun can be used against anyone but others with the DLC. Now, if they have "hidden" these weapons that come with DLC in the original Disc or will be providing via some mass update/patch to everyone, then I just can't see it working in standard non-DLC lobbies. I can see them doing it both ways, depends on how lazy they are.
There will probably be an update. I can't imagine that the gun would be that large of an update, as it's simply a model with texture placement info and "behavior" rules embedded into it. it will probably even use the sound resources of an SMG already in the game. It could be added into the game before the DLC, during a patch. It can be handled just like the CE Digital Camo... Everyone I play against can see it, they just can't use it on their own guns unless their account says they can. I also wouldn't be surprised if the 4 (one every quarter) DLC guns were already in our games somewhere.
Look forward to people spazzing when they pick the new SMG off the ground!
"ZOMG I just picked up the new SMG, I'm so amazing!"

Honestly though, if the new gun is a selling point, they will make it available in the core modes. It's just good business. Players will buy the DLC if they get killed by a weapon they can't put in their classes, and others will buy it after they pick it up and decide they want to have it too.
I agree. I think they have either hidden the guns in the original game and they will just unlock them or they will release a small patch that gives everyone the gun files so everyone can see it/use it if picked up. But, I can see them being so arrogant to not do this as well, thus the lazy statement - everyone is going to buy our awesome DLC right guys??? Given their response (i.e. lack there of) to the community, I give that more of a chance of happening than I would have previously thought.
