My apologies for the delay all. I can assure that the new content is done and in testing and should be released any day now.
Being on the cutting edge of a new service is always a challenge. What do you do with players from different countries, how do you handle people joining games with new content that others do not have, what content do you give a person in Europe with a US box?
All these issues and more have cropped up and are being resolved. The content has been done for some time and as much as I hate the delays, we all want to ensure the best possible play experience for everyone on LIVE.
Soon, very soon now.
