I'd agree - it seems like everyone is working a little slower this year. Possibly due to the snowstorms, etc. Also, looking here on GradCafe at the past few years trends, it looks like the next 30 days (between now and March 15) is when a lot of the B-schools start communicating acceptances.
Still it's hard not think that since I haven't heard anything - emails, phone calls, etc. - that I'm going to end up on the outside looking in this year.
