Since when does a few nights equal a "residency?" Sarah Brightman is doing like 3 nights in Vegas and called it a "residency." Anyway, their prices were insane and they clearly overestimated their appeal in this economy. Also, with each show having a different setlist, the cost would be astronomical for a fan who wanted to see all the shows. They need to be honest with themselves about their appeal.
I am sure they could have found a less expensive theatre option in the area to decrease their costs and allowed them to do a couple shows in NYC. If they really wanted to play for their fans they could have used New World stages, Theatre Row, or an off-Broadway house.
