Call of Duty : Ghosts had been put out on their site, with very clear packaging. The listing stated that 'Ghosts' is due out Decemer 31st, but that's more then likely just a holding date. The actual release will probably be around November.
At the moment, this is unlikely to be another Modern Warfare, due to the out-of-court settlement with former Infinity Ward bosses Jason West and Vince Zampella. So if Activision and Infinity Ward have pulled a brand new franchise out their heads, then ill really start looking forward to trailers and sneak peaks.
We'll keep you updated if we learn anything else!
