When does the Battlefield 3 Beta come out for the Xbox 360?

I got Medal of Honor Tier 1 Edition in stores for Xbox 360 and I got an invitation to access Battlefield 3 Beta. When does it release? Also, does it require you to access Battlefield 3 Beta through Medal of Honor Tier 1 Edition disc, same as what Microsoft done when you have to access Halo Reach beta through Halo 3: ODST?|||The Battlefield 3 beta will release within 12 months of the release of Medal of Honor. I expect you will have to access it through the Medal of Honor game.





Here are the official requirements for the Battlefield 3 beta:





"*Beta offer is contingent on beta availability within 12 months of Medal of Honor Release. Beta Participation requires Xbox Live Gold Membership, EA Account, in-game registration of online pass code and acceptance of beta agreement. Beta will be available for a limited time only and offer expires upon close of beta events. Must be 18+. Visit www.ea.com/beta for details, including availability."





The only way to activate your invitation is by entering the code given to you in the Medal of Honor Limited Edition or Tier 1 Edition game.|||Hello The Battlefield 3 beta has been released all ready for the xbox 360, the thing is loads of people don't know it has been released, if u want to get your beta key u can get it from where i got it.
