I suspect that those leaving now would be have decided to interview elsewhere due to the lead up to the August 24 D-day announcement. In other words they have been in the departure pipeline for quite some time. The October 29 act of economic vandalism (I am tempted to use a stronger word) does 2 things:
(1) Validates the decision for those who have gone. LWOP will be much more likely to stay elsewhere.
(2) Pushed those wavering to go. Many will now to decide to interview.
In all likelihood the Oct 29 event will probably not even begin to manifest itself in an exodus until February 2012 & beyond . Any current exodus is just a trickle before the flood.
Start drawing up your contingency plans.
