All I can say is Gustav Line is "done" from the development side of things. It's just a matter of getting the release stuff done. Because of the huge size it takes almost a day just to get the files ready for testing. Any problem means having to do that process all over again. So, for example, if we prep the files on Monday, testers start downloading during Tuesday. That's two days before any significant testing has been performed. If a problem is found then it's another 2 days, minimum, added to the schedule. Repeat as necessary until the problems are worked out.
