I haven't heard anything about PST disappearing. If anything, the other consultancies are starting to test out additional ways to sort out the applicants vs. a simple case (e.g., BCG giving a PST-like test in some offices, a written one in others, and regular cases in the rest). In any case - you should still prepare for it, PST skills are always useful when you need to do math or estimations on the fly during the normal case interview :) Good luck!
