Hello Saleem,
The current PM PrepCast that we offer is based on A Guide to the Project Management Body of Knowledge (PMBOK® Guide--Fifth Edition) which is also the basis of the current PMP Exam. For as long as PMI uses this edition as the basis for the PMP Exam, the PM PrepCast based on this 5th Edition will still be active and will not expire.
However, once PMI release a new edition of the PMBOK Guide (the 6th Edition, which is likely to happen March 26, 2018) the PMP Exam will be updated to reflect this new edition. The current PM Prepcast will expire on the date PMI implements the changes. Eventually the 6th edition version will expire once PMI releases another major update in the exam.
