A post earlier in this thred which was originally a email to Wingate residence said they should be done by the end of March, though I anyway doubt they made that deadline, I also think they only ment they will be done with the physical installations by then in that area.
As far as I know they usually finish with a entire area before lighting up the fiber, I for example know of a complex where the installation has been completed 3 or so weeks ago already, but they can't even say when it will be lit up.
I think June July 2017 is a realistic expectation, but the 6 months from now which you heard isn't that far fetched either.
