The easiest way to find out is to ask the shop through which you ordered your clubs.  When I got mine earlier this year, I was given a target time-frame and then had the fitter follow up with Titleist to determine the actual shipping date.  I ordered just before Christmas and had all my clubs by the 10th of January.  The irons and Vokey SM-4 wedges came much sooner, but I waited until the 24 degree 910H hybrid arrived before putting any of them into play.
