I can only speculate but I'm thinking that admissions may have gone down a bit as there is a lot of uncertainty in the Europe. Also, and of more effect, the LBS 2013 thread got started late (sept 27) so that will significantly cut down on the posts from non applicants, general questions, and ding/accept posts.
But, think of it this way, if the number of applications went down considerably, everyone stands a better chance of getting in this year
