Ghost is returning in MW3 but he is gonna be wallcroft have you realised whenever ghost was in a game wallcroft wasnt and whenever wallcroft was in a game ghost wasnt and they both hide their faces and they're voiced by the same person ( craig fairbass ). Ghost didnt die cos it was clear he was shot in the soulder not the chest and then more of the gas is put on Roach rather than Ghost and Before Ghost was lit on fire, remmeber his full body was covered so he probably didnt get burnt
