Oh boy, this kid has it all wrong. Lets clear this up. InfinityWard; developer team, makes MW3, Ghost Sledgehammer; developer team for AW TreyArch: developer team for BO1&2, also responsible for porting games to Ninty. Activision; sole owner to COD franchise. They are the publishers to all COD games. Activision will ultimately have the final say where they want their games ported to.
