Call Of Duty 4 Double XP Weekend

I’m currently working on getting everything organized and together for an upcoming Xbox Live / PSN promotion we have coming up the weekend of Sept. 13th - 14th. Which isn’t this weekend, but next weekend. I will have exact details on what it is in the near future but I have a gut feeling it’ll have Double XP attached to it for all those hungry for some power-leveling on Call of Duty 4.
