Call of Duty 4: Modern Warfare has been a huge hit, and Infinity Ward knows that.  Double XP has been music to any CoD4 player, and the weekends are packed with gamers flooding to prestige as quickly as they possibly can.  Robert Bowling, the Community Manager for Infinity Ward, posted the following in his popular personal blog:

"Back from PAX means back to work, and while it’s a short week thanks to Labor Day it’s the one time I wish it wasn’t because I have a lot of stuff to get done. 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.

Currently working on designing some Xbox Live banners to promote it on the marketplace and attempting to get everything together for it on our end. This promotion is technically unrelated to the new Playlists, but I won’t lie that my hope is to finish them up in time so that we can make it all one big promotion. How epic would that be? Our awesome QA team and producers are helping me push hard to make it happen by the weekend of the big promotion, no promises, but as always I’ll keep you updated on the progress."
