With all due respect until I hear otherwise this is still speculation. But in conversation with many diehard loyalists, many have said "It would not suprise me if the Society move out of Brooklyn altogether in the future - it would be safer for Bethelites not having to travel the subway to their congregations late at night, it would free up money to be spent on the worldwide work, and it is much nicer in upstate New York" -also I have heard the same about New York City just being too much of a juicy target for terrorists. In additioon there is still easy access to airports etc from upstate.
Bottom line , I have not heard the rumor but I do not think anyone (brothers and sisters included) who would be suprised by this move
