Body Building was expected to go while Basque Pelota is a hit or miss spot, though for Chile I thought they would be relatively okay with it. I had a feeling one of racquetball or squash would miss out, but seeing both was quite surprising. I imagine one of them will sneak back in.
Bowling is very surprising. It's been on the program for a long time and is one of the cheaper venues to build (just add some temporary seating to a bowling alley). The only major reason I can think of is money. It's not a huge spectator sport and the venue holds just a couple hundred seats so even though it doesn't cost a lot, it doesn't make a lot either.
