IGN has published what is allegedly a leaked display blueprint from GameStop revealing a date of May 1.
The news supports previous reports of a May unveiling and the announcement date would mirror the launch of Call of Duty: Blacks Ops 2, which Activision revealed at the same time last year.
The next entry in the popular military series will be called Call of Duty: Ghosts, should box artwork that leaked on to the Tesco website prove to be genuine.
Infinity Ward is believed to be developing the title for PlayStation 3, Xbox 360, next-generation consoles and PC.
Call of Duty: Ghosts will allegedly take place in the future, but utilise current technology and weapons in line with a "major plot event".
The single-player campaign is said to include more destructible environments, with multiplayer maps featuring interactive areas and traps.
