I think the new system is going to be mandatory for ocean flying,but I don't think they are going to get it through that fast for everyone and they actually have a system they are working on that can detect both current and new systems.Remember it was not to long ago that everyone was saying that VOR would be gone in a few years,guess what??it is still around.
