this will not be 7 or 6. WaW was not "Call of Duty 5: World at War" unlike cod 4. So if anything it will be 5. Also i have news, expect IW to make one for 2011 :p
I know you guys will think im on crack for this but what if, just what if CO7 actually is not about WW2??? LIEK OMFG COOL RIGHT? FOR ONCE? THEY MAKE A GOOD ****ING GAME? O.o
