YC has stated several times that they aren't releasing their statistics from now on because they don't want to get into a numbers war with competitors. They've released them for every past cycle; GIYF. It seems to be a good rule-of-thumb that 10% of applicants will get interviews, and 50% of those interviewed will get funding. I assume that the number of companies funded will still be disclosed (or at least, it will be hard to keep secret), so you can work backward from there.
