As of December 14th (UTC-7 22:50), Preparations for a Vast Revel lies at level 2618, 18 change points away from 2619.

From a bit of calculations, that would put the remaining (global) actions needed to bring the quality to 0 at just around 129k.

Amusingly, given the potential profit of "Purchase wine at cut-rate prices", 129k actions worth of wine payouts (at the highest rate of luck, of course), would total just over 3.1 million echoes, an amount of money nearly enough to bankrupt the Bazaar.
