There's not a whole lot of substance to the report, but Joystiq have noted that during a PAX East panel presentation, both Epic Games' Creative Lead Cliff Blezinski and President Mike Capps dropped mention of an upcoming game from the studio that will be exclusive to PC.
We might be working on a PC-only title," Capps teased, before Bleszinski picked up where he left off: "Let me say that again: we are working on a PC game."
Having made their fortunes with the proudly multiplatform Unreal Engine technology and the Xbox 360 console-exclusive Gears of War series, the promise of a PC-tailored game from a studio at the forefront of rendering technology is quite tantalising -- particularly after hearing that their Samaritan tech demo (embedded below) can run in real-time on Nvidia's new GeForce GTX 680
However, the definition of "exclusive" is used rather flexibly these days, so perhaps it means "PC only, to start with", or just "not console" and will be on mobile devices and Mac as well or could just be a casual/social browser-based game that most of us probably won't be interested in, but we're going to hope it's something that looks and plays like Samaritan anyway.
Epic Games are also currently working on a new multiplatform property called Fortnite, a cooperative fort-building, zombie invasion game, as well as Infinity Blade: Dungeons for iOS.
