Aside from their twitter, it could just be that there's nothing for them to actually update people on; personally, I consider such an 'update' to be "Hey, we hit a snag and won't make the release window". As far as I am concerned, no updates on the state of the game is good news because people would really only truly care, and thus circulate said news, if it was bad news. Good news is fantastic, but not really an important update, 9 times out of 10.
