Epic's first game running on its next-gen Unreal Engine 4 will ship in 2013.
That's according to Epic boss man Mark Rein, speaking during a video interview with Joystiq.
When asked when the first UE4 game will ship, Rein responded, "I don't know. For sure something next year, I just don't know exactly when."
He went on, "Until we're really clear on when the game is going to be finished, when the partner wants to put in the sand and market it, we don't really have those kind of dates."
Later in the interview, Rein said, "It's certainly important for us to have our flagship game. That's the game for which we develop the engine. Gears of War was the game for which Unreal Engine 3 was developed, and so shipping that has a huge significance for licensees and for us. I think, for Unreal Engine 4, there'll certainly be a couple of games."
If you're still yet to see the immensely impressive Unreal Engine 4 Elemental Showcase demo video, you need to do that right now.
