It is unlikely that Verizon will/can shut down copper telco service for a long time. The infrastructure to support FiOS still does not exist in many areas where FiOS has a presence e.g. NYC. Until Verizon is available to every single location where copper exist today, copper isn't going away.
Actually they are definitely sending out notices such as the original poster mentioned hear in Nassau County, NY. Might take longer in NYC, but they are definitely moving to get rid of copper which is high maintenance.
