GamesCom has revealed that Call of Duty: Ghosts will receive dedicated severs through the Xbox One cloud service. This breaks years of peer-2-peer connections services that have come to define the series on-line experience.
It's nothing to rejoice about just yet, though, as it is still "unknown" if other platforms will be receiving the same treatment. These dedicated servers are utilizing Microsoft's own services, after all, and are no indication of Activison laying out the cash for true dedicated servers on Call of Duty: Ghosts.
It's also important to note that during the Call of Duty: Ghosts mutliplayer reveal a host migration was caught on video. In the very least this indicates that some builds of the game are still running off peer-2-peer connections. Given that Activison has had no issue with these type of connections on current generation versions of past Call of Duties, I wouldn't hold your breath for dedicated servers on either the Xbox 360 or PlayStation 3.
The news didn't stop there, as Activison has also revealed a Call of Duty: Ghosts Xbox One bundle for Europe that will ship with exclusive content when the system launches later this year. Activison has yet to talk price, so stay tuned as more information comes out of GamesCom.
