The PlayStation 4 will soon support pre-loading via the PlayStation Store, starting with Transformers: Rise of the Dark Spark, due on June 24. As will be the case with all pre-orders going live after May 20, Sony says, you'll be able to download the game's files a few days in advance of its release date (even from standby mode), after which it will become unlocked on your console.
