Tokyo Wins Bid To Host 2020 Olympic Games.

                               
Tokyo and Istanbul have advanced to a final runoff vote to be the site of the 2020 Olympic Games.

Saturday's International Olympic Committee vote in Buenos Aires eliminated Madrid.

The IOC is expected to announce the winner during a ceremony from 5 p.m. to 5:30 p.m. (4 p.m. to 4:30 p.m. ET).

Each of the cities has strengths and potential weaknesses, said Ed Hula, editor and founder of aroundtherings.com, which covers the business and politics of the Olympic movement.



"Istanbul is the one bid that offers something unique and different," Hula told CNN in a telephone interview from Buenos Aires.

If Turkey were to win, it would be the first Muslim country to host the Games and, with a median age of less than 30 years, one of the youngest.

"Those things make Istanbul a more emotional choice," Hula said.

But the city would face daunting logistical challenges, including the need to modernize its transportation and venue infrastructure.

Though unrelated to its bid, Turkey's border with Syria could also prove problematic to some of the committee members, he said.

And this summer, the image of Turkish sport took a hit when about three dozen athletes tested positive for drugs, he said.
