We have also heard from the developers that the previous games would be cheat free MW2, Black Op's and MW3 but they were/are all infested with them.
The dev's said the games would basically be lag free, but with all the games MW2, MW3 and Black Op's there was lag even when connecting to servers/host's within the same town/country.
The dev's said the games would be optimised properly but they were not.
The dev's said we get pc exclusive features, however I have not seen anything that could be classed as pc exclusive considering they only added what was removed from the games back in to them.
I will believe all the "facts" when I see a video of the pc version and a official statement saying what features are in the pc version, but because we are pc gamers we will not see pc exclusive gameplay because they won't show anything other than the xbox footage as that is there primary market, and they won't give a official statement because they know they will be ripped apart once the game is released if it is not how they stated it would be.
No doubt once the game is released and I post a review in my oppinion on it, on here I will be banned and the review will be ripped down within a hour because I am very confident the game will not be as good as they dev's will say it will be but you never know they may suprise everyone.
