Unfortunately, not enough to plan any games for the immediate future. They have been averaging around 150 for the past few years and it wasn't worth shutting out the open play and groups, according to the owners. They put a lot of work into the big games and had IMO the best refs, which everyone says but I really mean it, they work their butts off for you. They also brought out the same air supplier as Living Legends, which they have been doing for years.
After the last game, Joe announced that they are not planning any future big games. Hope is still there, but not likely in 13.
