i would like to see th Commando come back. that was a beast of a gun in Black Ops.
Would probably be easier just for a skin change for a bunch of the weapons given a lot of them "are" in the game, just in different form...like the Commando is pretty much the M27.
I agree with the aug but I like the mw2 version over bo honestly
Ill go out on a limb and say akimbo lmg's
