You can look at your stats for MW3 BO, BO2 but not Ghosts as of yet?
I don't think it will. This game cater for clans/pro teams who can view all that through the clan app. You can however see your stats and anyone elses in pregame lobby by highlighting your gamertag and moving the right stick to the right. Hope this helps.
Never. Hang on a sec and will provide an official link...
the FAQ: Call of Duty®: Ghosts Clans FAQ
Q: Why is there a new Clan system for Call of Duty®: Ghosts?
A: Clans in Call of Duty®: Ghosts will include deeper in-game integration and more features, from in-game Clan Management and Clan–specific playlists to the all-new Call of Duty® Clan Wars game mode available in the new Call of Duty® app. This year also introduces cross-platform Clans, allowing players to create and/or join a single Call of Duty®: Ghosts Clan across the following platforms: including Xbox 360, Xbox One, PlayStation®3, PlayStation®4 and Windows PC.
Q: Won’t my current Call of Duty® Elite Clan work with Call of Duty®: Ghosts?
A: No, Call of Duty®: Ghosts Clans are built on a new system, so Call of Duty® Elite Clan Leaders/Members alike must start or join a new Call of Duty®: Ghosts Clan.
Q: When Call of Duty®: Ghosts launches, will the process of creating, managing, and joining a Clan be the same as it was during the Call of Duty®: Ghosts Early Registration?
A: No. On November 5th, 2013, you will be able to create or join a new Call of Duty®: Ghosts Clan by downloading the new Call of Duty® app on your supported mobile device. Through the Call of Duty® app, you will have full access to a robust Clan Management system, among many other features designed to work hand-in-hand with the Call of Duty®: Ghosts game. We will have more details to share on this process at launch.
