A few US managers that are normally very talkative/open about pending/planned RAs are now radio silent, no response at all. That feels a bit ominous. Maybe there was a meeting at Think or via conf call and everyone was called on the carpet about leaks. They may have been given the date, finally, and a strong warning to not say more if it's about to go down.
Friday, last work day in the month/quarter, makes the most sense now. With two weeks notice, folks will be cut loose right around tax day in the US.
