I think the game + engine costed sony around 60 million + marketing 10 million =
70
70 : 3
2,5 million
but they already shipped 1,1 million to europe so i think they will make huge profit with KZ2 and what is more important
with killzone 3 they will have a systemseller next generation
btw:
cod world at war sold good because it was released in the holydays but killzone 2 will have good legs because of word of mouth so it will reach 3 million at least
but more likely 4-5 million lifetime
sorry for my bad english
