Epic's President Mike Capps and Cliff Bleszinski let slip that the studio was currently working on a PC exclusive during a PAX East panel this weekend.
Capps told Joystiq post-panel that work on the unnamed game was underway, after only teasing it during the talk.
"We might be working on a PC-only title," he had stated, for Bleszinski to confirm the news a beat later: "Let me say that again: we are working on a PC game."
