Call of Duty studio Infinity Ward may be developing for the Valve-backed Piston mini-PC from Xi3.
The developer has posted an image of what appears to be an Infinity Ward-branded Piston to its Facebook page along with a caption that simply reads "game development."
Infinity Ward posted a similar image to its Twitter account, writing "What's this?"
An Activision representative was not immediately available to comment.
Xi3 announced the modular, grapefruit-sized computer designed around Steam's TV-focused Big Picture mode during the Consumer Electronics Show in January. Valve itself at the time announced that it had invested an undisclosed amount in Xi3.
As for the Activision-owned Infinity Ward, the developer recently moved into a new office space and has no announced projects. Last month, Activision revealed that a new Call of Duty game will release in 2013. Executives do not expect this game be as commercially successful as immediate predecessor Black Ops II.
