Out of interest will UAV/UAS's will completely take over some roles apart from passenger transportation, some law enforcement and EMS operations, because of zero risk to aircrew and cost attraction?
What about the risk to others below and around the UAV/UAS?? It would be interesting to see how that risk has been calculated. In the event that manned helicopter has to force land for some reason, at least the pilot can assess the various options open to him for landing without causing damage to the aircraft and/or other persons/structures. I'm not so sure that the person controlling a UAV/UAS would be able to do the same as they wouldn't have the advantage of "all round vision" and thus be able to assess various options quickly.
