I will post when I see any official announcement.
As for future locations, things like travel connections, hotel cost, a large enough venue, local beer scene, active clubs, and local laws pertaining to Homebrew at the conference all go into the mixer and eventually a site is selected by the AHA.
So Jim, I think NYC would be out on the cost issue. The NHC has been in LA and Chicago, but not recently, so cost and size might not be in their favor.
