I just thought of a major factor in GoW’s favor. GoW has traditionally done much better, sales-wise, in the US. GoW 3 still sold great, despite the ps3 selling fairly poorly in the US. But for the new God of War, ps4 has a very healthy install base in the US.
It would be interesting to compare the US sales numbers for ps3 when GoW 3 released vs. ps4 now when GoW is releasing.
This GoW is more targeted at Europeans than previous installments. So I would expect a 6:4 salesratio in favor of the US. But this game should be able to sell 2 million during the launch week. With 900k coming from the US. This is going to be the best selling GoW game to date however.
Please excuse my (probally) poor grammar
