Not sure about including cricket in the olympics. I'm more of a purist and see T20 as more of a fun 'hit and giggle' version of the game. Real cricket (test cricket) already seems to be dying somewhat of a slow death and I wouldn't like to see T20 glorified to the extent that it becomes more important than test cricket. It would be pretty cool to see in the games but I would hate for Australia to start taking it more seriously than the real version.
I'm not an expert, but when it comes to club rugby, like (american) football, don't they only play once a week because of how physical it is? teams need time to recover after games, so rugby would never work in a 2 week competition
I was under the impression that sevens would be in for 2016. Seems to be a little less physical making it more realistic to complete in the two week time frame.
Also, I heard rumors futbol (soccer) may be on its way out. I have a hard time being ok with trampolining and race walking being in, but baseball and rugby being left out.
In case anyone was wondering, these sports (which aren't in the Olympics) governing bodies are recognized by the IOC, which is a requirement to become Olympic.
Auto Racing (provisional as of 2011)*
Mountaineering and Climbing
Tug of War
*Couldn't be in the Olympics due to rules that say sports can't rely primarily on mechanical propulsion
Don't know why so many people are saying baseball and softball. I think they were pretty justified in removing them from the games and it hasn't been long enough for things to change. Maybe they'll be back 20 years from now but not after just one games.
