It looks like Sony might have accidentally spilled the beans when they listed what appears to be the next Call of Duty title on the PlayStation Store. The image above shows the mishap.
According to the leak -- which was first discovered by someone on Reddit while browsing through the Trending section of the PlayStation Store -- the next title in the blockbuster series will be Call of Duty: Infinite Warfare, though Activision have yet to confirm this. The publisher have, however, previously stated that it will be a "new and innovative Call of Duty title."
Activision usually make their annual announcement regarding future Call of Duty titles around April/May, so it is likely that the publisher will reveal the first batch of details surrounding Call of Duty: Infinite Warfare soon.
Given that Activision introduced a three-year development cycle for Call of Duty, it's Infinity Ward's turn this year. The last Call of Duty game created by the developer was Call of Duty: Ghosts in 2013.
