At Son Lux last night I spoke to Andy who many ATP NY-area folks will recognize as head (?) of security for all of the area festival incarnations (and many other shows around NYC). He said that they are working on planning a new one, looking at Long Island this time where they could go back to more of the holiday camp-type vibe after the problems of the in-city attempt. I don't know LI that well but I totally buy that there could be the right style of resort/hotel/venue clusters that would make a great off-season spot. Not necessarily 2014 but they are not abandoning the market.
He also mentioned a related (?) event is coming back (for 2014) but right now I am blanking on what that is.
