Btw you shouldn't forget that there is more as selling consoles if you fund such a game. There will be many people paying for Gold only to play this game on 360 and also a few on XB1. That's also a reason why the time of the release was good, around half a year after and before the other big shooters like CoD.
That as example is also something which will be in Microsoft's calculation but is probably not in most forum users calculation, that there are a lot of people who buy Gold only to play some shooters for some months and stop paying until the succesor releases.
