One of the major surprises from the Call of Duty: Ghosts multiplayer presentation is that players will be able to transfer their COD account from current generation consoles to next generation systems using the Call of Duty app.
This includes all your character progressions for your squad as well as purchased DLC. Transfer of DLC will only be available to those who purchase the Season Pass.
While hardcore fans will probably be buying Call of Duty: Ghosts on its release day, the same can’t be said if they will buy a next generation console as well. With the ability to transfer information using the Call of Duty app, it doesn’t really matter as your information will come with you to the next gen console whenever you upgrade.
Infinity Ward also revealed that clans will support members playing on current and next generation consoles.
