Speaking to G4, Epic Games’ vice president Mark Reign revealed that the company will be publicly showing the successor to Unreal Engine 3, appropriately named Unreal Engine 4, before the end of 2012 and promised it will have a “profound” effect.
Specifically, Reign said:
“People are going to be shocked later this year when they see Unreal Engine 4 and how much more profound an effect it will have”.
Despite the planned reveal this year, Epic Games has stated in past interviews that they don’t expect to have any games released that use the engine until “around 2014”, so no matter how “shocked” you are by whatever they show off, keep in mind that we still have a bit of a wait before we can get our hands on it.
