Call of Duty: Ghosts will support dedicated servers not only for PC, but also for current- and next-gen consoles as well, which probably includes the Xbox 360, Xbox One, PlayStation 3 and PlayStation 4.
Executive producer Mark Rubin "I wanted to give a quick update on some of the work that has been done to improve everyone’s online experience. We’ve already mentioned dedicated servers as part of the overall plan to improve connectivity. Dedicated servers will be used on current gen, next gen and PC with Ghosts. And, in order to make sure that people have the best possible experience regardless of platform, location or connection, Ghosts will be using a hybrid system of dedicated servers and listen servers."on Twitter,
It's doubtful by "current- and next-gen" that Rubin means the WiiU.
Call of Duty: Ghosts will be released this November 2013 for PC and consoles.
