We're not in any defined 72 hour window at the moment. The developers have proposed the following schedule:

{some unknown time from now} -> release of new (beta?) wallet

{some unknown time from release of beta wallet} -> 72 hour warning of upcoming verification

72 hours after warning -> 72 hour verification period begins

72 hours after verification period begins - verification period ends and new Aircoins are deposited 1:1 in - where? Another wallet, I suppose. Which we'd have to have before they can deposit/giveaway the matching coins.
