Well, it probably wasn't delayed by only 2 weeks because of the massive amount of games that were coming out then, for a marketing standpoint, the 20th would be best (also for day 1 digital download since psn updates on tuesday). Plus they will have extra time in polishing.
I remember seeing that it wasn't going to be a day 1 digitial. Also that wouldn't matter with delaying because digital is already out. The extra time bit is slightly true though. Mostly this is just going to be small changes though.
