For Berkeley I do not think there is any chance without an interview. I have heard from multiple sources (incl. students being interviewed last year and on year 2012) that Berkeley will interview all shortlisted candidates, which implies that if no interview was given at this time then the chance is slim
For MIT I believe interview is for borderline candidates only. This could be proved by previous years' results.
For CMU I am not pretty sure about their policy because CMU has a fairly large CS department (i.e. SCS) and a few departments underneath SCS, such as ML, LTI, RI, CSD. Different departments make decisions separately and might adopt different policies.
I myself also applied to top CS PhD programs and is anxiously waiting for results. I will kiss my own ass if Berkeley admitted me without an interview (haven't received one...), but for the rest I stay optimistic until mid-Feb. Berkeley mass acceptance is likely to be Friday or next week; while MIT may send bulk acceptance during the first week of Jan.
Gook luck to everybody!
