Activision has found a great way for people to upgrade to next-gen consoles, and if you buy Call of Duty: Ghosts on the PS3 and Xbox 360, you will be able to transfer your stats to the next-gen consoles.
There will be a Call of Duty account which makes this really simple. The game received a multiplayer blowout recently and the full presentation footage is also out. If you buy the Season Pass, it is also transferable so Activision really wants you to upgrade.
The game comes out on November 5th on the current gen consoles and PC, and on the same month on the next-gen consoles as well. Call of Duty: Ghosts Hardened and Prestige Edition have also been revealed.
