I could look for it but i don't have the time perhaps you should look for it you are the one that wants it on the xbox after all it would really sell your point to others. what i remember seeing was that
mgs4 = 60-100 mill budget Konami made mad profit
GTa4 = 100 mill
kz2 = 40 mill
even if kz2 was 100 mill+ it will easily recover it i willing to make the bet it will be 4mill ltd
