"There are no plans to bring Call of Duty Elite back." So says Activision in a rather straight-up, no messing sort of a way regarding its CoD Community set up to augment games prior to Ghosts. Elite will, in fact, die this Friday, February 28th 2014.
The statement goes on to state that, "We encourage fans to download the Call of Duty app for Call of Duty: Ghosts, which allows players to customize their multiplayer character and weapons loadouts on the go, keep track of their Call of Duty: Ghosts stats, and features Call of Duty Clan Wars, where players can compete for cool, exclusive in-game gear."
So, yes, there will be a replacement after Elite's death on February 28, 2014 at approximately 10:00 a.m. (PST). In fact, stats, clans, video content, even Founding Member badges and status will all be available in the new Clan Wars.
The only things you won't get according to Acti/Blizz are your Clan's medals from Clan Ops and Challenges.Full FAQ is here.
