As soon as we have information to share, we'll be sure to pass it along. We're very well aware that users are looking forward to pre-ordering on PSN, but we're still working with Sony on making that happen.
We've not forgotten you all, but it does take more time than the physical pre-orders. (There are a lot of moving parts to consider!)

You will be able to pre-order it, and receive the pre-order bonuses, ahead of launch, so don't worry.
