I'm guessing based on previous releases they won't have any problem selling out in a week or a couple of weeks at most, because the main impact here is likely going to be on people scoring 3x or 4x per person beers on both Wednesday and Thursday (which I'll certainly admit to having done).
It would be kind of funny though if the last few bottles of something fairly expensive like CD11 sat around for a while simply because all the semi-regulars you mention already got it, and none of say, the local/tourist crowd who go in for growler fills were interested in dropping $35 for a 750ml saison.
