It was unlikely to remain even without reducing the number of sports. Basque Pelota should be in danger, but Chile will likely push for its inclusion. Surfing will likely be cut unless it stays on the Olympic program in which case it will likely have reduced events. Skateboarding is on the same boat as surfing, but I'd argue it has a better chance of surviving should it get cut from the Olympics. If there's a push to remove more established Pan Am sports I imagine water skiing will be a likely candidate, perhaps one of Racquetball or Squash if people start to argue that we have too many racket sports.
