It appears an unknown studio, Pitbull Studios are assisting Epic Games with their Unreal Engine 4 and also working on their first game in the brand new engine.
We know this because of some job listings which were listed in LinkedIn.
The listings for positions at Pitbull reveal the studio is “working on Unreal Engine 4 with Epic Games,” and also, “games derived from that and Unreal Engine 3.” Positions also vary from environment artists to engine programmers, with many other roles in between.
Epic revealed this to Joystiq, and also offered a statement from directory on engineering, Daniel Vogel.
“Epic has a great history working with Pitbull Studio. We can count on them to provide reliable engineering resources, and they’re helping us prepare for the next generation of games.”
