New Olympic sports to strike gold

We are rapidly heading towards an IOC decision about which new sports are set to be included in the Olympic Games, and a number of sports are therefore jostling for pole position as they seek to gain entry. Why? According to Sports Illustrated, for the period 2004-2008, the IOC awarded $256 million to the Association of Summer Olympic International Federations i.e. those federations responsible for running those sports included in the 2004 Athens Games. Of this total amount, track and field athletics was the largest recipient receiving a reported $12.5 million. Pulling the above details together, on what basis are sports retained, accepted, excluded and rejected as Olympic sports? Is it on the basis of the consistency with and support for the IOC's core values (in other words, is it organisational and socio-cultural)? Or is it more to do with the nature of the sport and the format it takes? And what role economics and commerce? Are sports with media, specifically broadcaster, appeal and sponsorship potential more likely to make the cut? In which case, do sports that are a short, sharp spectacle with global appeal (possibly allied to strong community development programmes) constitute the ideal to which the IOC aspires for new sports? Are there some sports therefore that are inevitable favourites? And some sports that don't stand a chance? Interesting to ask: would test match cricket or one day cricket stand a chance of making an Olympic Games? Or would 20/20 Indian Premier League-style cricket be much more likely to be included?
