Yea, I really hope they fix this in the future, having a game chat channel is a plus and cuts out the un-needed leaving the party entirely to go chat to some one, then needing another invite to the party to get back in.
ALSO, I know this isn't the right topic for it, but I really think they should have some type of way to set controls/sensitivity for different game types, I always find myself right at the beginning of an arcade or realistic game pausing to either, lower or raise the sensitivity..
