Sony has changed its refund policy to allow people who purchase pre-orders on digital titles to have them refunded at any time prior to the release date.
In the same change, Sony also now allows refunds of games past the purchase date (or release date in the case of pre-orders) for up to 14 days after payment was taken, provided the game has not begun downloading or streaming yet.
