That's the question many of us are wondering as well. It's pretty obvious that they are not reviewing applications in order of completion date, since people have received all sorts of decisions--II, hold, reject--already while others who were forwarded for preliminary review long ago, including you and me, haven't heard a peep.
At this point, I'm going to go ahead and say that both silence and "hold" statuses mean we are still theoretically in consideration, which is better than outright rejection, which several applicants have gotten so far. If I speculate any further about all of these school's admissions protocols my brain might pop!
