I am honestly getting confused by the amount of faith some seem to have in halo MCC on the XB1.
And as for your COD:AW, I think people are also mistaken the fact that because COD usually sold more on the 360 its an always had xbox bias marketing its an xbox game.
Here's a little something to consider;
PS3 NA total = 28.62M
360 NA total = 47.37M (~40% more than PS3)
Call of duty MW3 (2011) = PS3, 5.4M and 360 8.7M (+40% approx)
Call of duty BO (2010) = PS3 5.8M and 360 9.3M (+40% approx)
Do it for all the other call of duty games, the games simply always just sold to the tune of the available install base. This is why I am never of the inclination that COD is an "xbox" franchise.
