A rumor regarding the prestigious Call of Duty 4 development studio Infinity Ward has been swirling around the internet as of late. According to Talk PlayStation's "inside source," Infinity Ward is supposedly working on a new sci-fi title which they "may or may not announce at E3."
Frankly, with the vague information given coming from a site without repute, we wouldn't consider this information reliable whatsoever. It does seem possible that Infinity Ward could develop Call of Duty 6: Future Warfare however. If that's the case, don't expect any solid information until after Call of Duty: World at War has been released for several months.
Whatever ends up happening, we'll be here to cover it. Stay tuned.
