PSA time
Infinity Ward no longer exists. They did not make MW3. At the very most, they made the modifications to the engine that allows scripted environment destruction and the general plot. The art, design, and even more engine modification was done by Sledgehammer, a studio Activision cobbled together after they showed the IW guys the door. The former founders of IW have since moved to EA and formed a new studio called Respawn Entertainment.
History has repeated. The founders of IW made Medal of Honor Allied Assault for EA. After that they were given the boot. They went to Activision and formed IW and set their sights on the franchise they created. Sure enough Call of Duty on the PC blew MoH away. Back in the present, they are going to tear CoD a new asshole just like CoD destroyed MoH.
But really, Infinity Ward stopped existing like a year ago. (maybe longer?)
