I second dodge ball. They'll have to come up with a universal rule though. It seems to be totally different depending on where you're from. polo (yes, on horseback) It was on before but got discontinued... maybe too many horse injuries.
I think a majority of the countries have to play that sport for it to be placed in the Olympics. I don't remember the exact rules, but I remember reading about it somewhere. It's nice that they added snowboarding to the winter games. I can't think of anything else that would be a good olympic sport. :/
