There are two possibilities:
1. EE system is dependent on the government. I mean, if it requires some kinds of reviews of each applicant, signatures of higher-ups, etc. etc.
2. EE system is fully separated from the government, and they only supply each other some kinds of regulations and reports.
In first case scenario - there is a big chance that there will be no draws for 2-3 weeks or even a month. They will need to assign people to operate this process, maybe even review it's internals, and all this takes time and money. However, this also means some changes (be it good or bad) after the draws continue. New employees could be faster/slower than old ones, or could decide to make draws happen more often but with less people in each, and so on.
In second case, this 3 week delay is a mere statistical error which will get corrected over time by itself. In this case, I believe that (my personal opinion, no strong arguments) the score will drop but that will happen much slower than other people anticipate. We could see something like 460 - 453 - 450 - 449 - 449 - 448, etc. The reason I believe it is an actual score statistics: http://i.imgur.com/4MqdAQz.jpg . The chart is a bit outdated, but you can notice how strong the CRS 450 limit is. I guess that amount of people at each mark grows exponentially and if we combine all the influx of people with scores of 450+ over the 2 weeks, we would get very close to 1500 persons, that is, to the draw count. That would mean, that the 449 score alone could house 500 or more people. So, it will slowly drop, but that will happen much slower than we hope.
. I think now they will focus on processing those who have been issued ITA. Well let's see how it goes.
