IOC President Jacques Rogge said on Tuesday that a decision on the host city for the 2016 Games would not be driven by economics, but the sustainable legacy hosting the event would leave.

As well, seven sports are looking for inclusion at the 2016 games...but only two will be selected.

IOC President Jacques Rogge said, "We want a good warm public and we want also, whenever possible, great success for the home team because it gives a lot of ambience and atmosphere and ultimately I would say it is not economics but leaving a sustainable legacy because when we leave we want this to be a bonus for the city, for the region and for the country."

Rogge was speaking at the end of a two-day Executive Board meeting at the International Olympic Committee Headquarters in Lausanne, Switzerland.

The IOC Executive Board meeting will be followed by the 2016 Candidates City Briefing. Rio de Janeiro,Chicago, Tokyo, and Madrid will all have a chance on Wednesday to show the IOC why they should be chosen to host the 2016 Olympic Games.

The Olympics have never been held in South America and Rio is hoping that will count in their favour as they bid for the 2016 games. And Brazilian President Lula da Silva stepped up his country's bid for Rio de Janeiro to hold the Games.
