I don't think there is anything to be worried about. There haven't been any posts in the admissions forum about slavic programs except, I think, for rejections from Princeton (and they have particularly early deadlines). I think Berkeley has the earliest deadline (mid December versus early January), so they are likely the first people you'll hear from. And from looking into the admissions announcements from past years, people usually don't hear anything until late january at the earliest (around now, to be fair) and only from Berkeley. The rest of the notifications, at least for the programs I follow, come throughout february and march.
I can say that I received request for an interview last week from Yale (and posted about this in the admissions forum). I'm not sure if they are doing those one off, or if there were a whole bunch sent out. The problem, really, is that people applying to slavic programs don't seem to be very active on grad cafe, and that makes for difficult predictions for people in our situation.
Best of luck, and keep us all posted if you hear anything.
