No, it is happening now. Many have already taken it. Prometrics is administering the exam. Current PTIN holders have until 12/31/2013 to pass the exam (it is pass/fail) or not have their PTIN renewed. Money has been spent and review courses taken. I'd be a little po'ed if the program was not at least continued as optional.
In this case, procrastination has proved to be a great virtue! :-) I hope this decision is upheld if the rev’nooers decide to appeal.
