I am in the same boat. I really think something weird is going on this year...CLS, SLS, HLS, and YLS have all only admitted auto admits (more or less) up until this point. That means the applicant pool is either unusually strong, unusually weak, or unusually small (since according to LSAC data it's not large). It seems that alot of people with strong numbers are still waiting to hear. On the other hand, there have been some pretty surprising dings/deferrals. Which means that the app pool may be particularly strong this year, albeit smaller, so schools are doing more strategizing as far as yield protection and such. With app deadlines coming soon, I think there will be a flurry of activity in the next 2 weeks or so.
Maybe they are saving the rejects for last because they have no need to tell you since you are not coming.
