While talking to a distributor for MS today I was told a new update is in the works. He went on to describe how Microsoft Reps told him that before the "Official Summer Season" has ended a new update roll-out for Xbox Live would be implemented. This may not seem a big deal, however he mentions "Group Chat" was in the works. He stated that up to 4 players could communicate by Seasons end over Xbox Live.
Hopefully we can put those "Private Chat" days behind us.
