According to the latest committee conference resolution, there are total 31 Olympic sports and 9 non-Olympic sports, total events/gold medals around 460-470.
31 Olympics sports - no skateboarding and surfing (including sport climbing, karate and softball/baseball )
9 non-Olympics sports -Wushu, Sepaktakraw, Kurash, Jujitsu, cricket, Board games, Roller skating, Kabaddi and squash
I think sports are basically confirmed but events are not totally confirmed yet.
