Sorry has been asked, but if I pre-order the digital download code from Amazon, does that mean I can't pre-load from the PSN before the game releases? Their page says:
"You won't be charged for your pre-order until the product is available for download. When the product is available, you will receive an e-mail reminder that your download and product keys are in Your Games and Software Library. You can also go to Your Games and Software Library anytime after the release date to download your product."
Which implies the code isn't sent until you are charged, which would be at midnight 9/9.
They send the code usually on release day and sometimes well into the morning, so pre-loading is highly unlikely.
This is why a lot of us bought PSN cards from Amazon and just bought the game through PSN.
