My own theory is that after watching Iran kill themselves for a year trying to figure this thing out, they sent out an update of Stuxnet that made it easier to discover as a way of showing their hand.
By that point, according to most reports, the program had been set back by three years (as effective as what a military strike would have been, according to the NYT article).
It was hidden for almost two years, then suddenly discovered - at which point dozens of security companies around the world deconstructed the worm in a process that took weeks.
