Either they ran out of ideas or they didn't have time to finish the two weapons in time for their respective releases. It would've been nice, and easier, to have brought back some of the older weapons from the MW series; like I would've love to see the return of the M16 from COD4, 3-burst FAMAS from MW2, or Type-95 from MW3 (Ghosts could certainly use another 3-burst-default weapon in its list, even though there's the burst-fire attachment, no one uses it)
