Considering that the game only had 2 days sales i think that almost 400,000 sold is great! I mean thats the best opening of any PS3 game released so far isn't it?

 Two days of sales for a game is normal for first week, though. Nintendo for example always releases its games on Fridays and most other publishers are doing so, too.
