The much anticipated Title Update 3 is out of certification and is going live on March 24th at 2 AM PST/5 AM EST. Please remeber it takes awhile for the update to propagate so it may take up to several hours after that time before it's available locally. Also, if you start getting matchmaking connection issues, it means others have the update and you don't, so please exit the game and fire it up again in order to download the update. Also please note that some of the new achievements require the next map pack "Snowblind" which will be released next week.
