Initial PVB paperwork indicated completed winter 2016.
The latest guesses range from January 2016-July/August 2016. Part of the reason for the later guesses is because they are behind schedule. They delayed work for the July 4 crowds.
It is possible it could be done by March, but most seem to be expecting a summer 2016 completion schedule.
If you are concerned with it being completed by March, it may be wise to plan on another resort.
