I really don't see how a 'gun pack' would be able to be accomplished delicately enough to be effective and balanced.
Why not? Look at Team Fortess 2, that has a crapload of guns and gadagets I'm (currently) not allowed to access, and were periodically introduced into the game, yet I wouldn't say the game was unbalanced in my favour*. It just gives the players more choice to kill each other.
*Mostly.
Friggin' demosword.
edit: Just had a thought. Yay! The Team Fortess universe allows weapons to do some extraordinary, unrealistic things, yet MW2 weapons will have to have a semblance of realism. So this a new weapon pack likely means we'll either get a set of identi-weapons (lookin' at you, assault rifles) or OP weapons (lookin' at you, erm... massively powerful piece of army equipment?)
Enthusiasm = waned.
