yea its not updating for me either on xbox
same on PC.
As I understand it:
1) servers are pulled offline (or Ed falls over the plug...)
2) servers are updated. This may take anything up to (hopefully not more than) 10 hours.
3) at some unspecified time during these 10 hours, might be sooner, might be later, the download is enabled for the clients
we are currently between 2) and 3). As to when 3) will happen - well, the guys and gals at FD are fighting against the most fundamental law of this universe, so just let them get on with it.
