Well all i know is this, they said CoD would be Dx11 ready but sadly later on they said that it didnt make the release but Dx10 would, sadly it looks like Dx10 didnt make it either by new players accounts, but logically in time it will.
So will Dx11 and 64bit, think about it, its plastered all over every advert and even the manual for the game, Dx10 & Dx11 technology and Dx11 surely cant exist without with 64 bit.

Maybe its not on initial release but if it didnt come in the patch, it would leave the door wide open for people to call in a breach of the trades discription act, and no fancy lawyer could defend them from that.
I think the guys at 1C have more brains than you give them credit for, they know the West has a compensation generation, they arnt gonna walk full face into that one.
