Potential first-ever golds/other medals at London 2012
80 of the 204 participant countries at London 2012 will come into the Games without having ever won an Olympic medal. They are:
AFRICA - Angola, Benin, Botswana, Burkina Faso, Cape Verde, Central African Republic, Chad, Comoros, Congo-Brazzaville, Congo-Kinshasa, Equatorial Guinea, Gabon, Gambia, Guinea, Guinea-Bissau, Lesotho, Liberia, Libya, Madagascar, Malawi, Mali, Mauritania, Rwanda, Sao Tome & Principe, Seychelles, Sierra Leone, Somalia, and Swaziland
Botswana - Amantle Montsho is the current world champion in the women's 400m in athletics, and made the Olympic 400m final in Beijing.
ASIA - Bahrain, Bangladesh, Bhutan, Brunei, Cambodia, East Timor, Jordan, Laos, Maldives, Myanmar, Nepal, Oman, Palestine, Turkmenistan, and Yemen
Bahrain - In Beijing, Rashid Ramzi won the gold in the men's 1500m in athletics, but he was disqualified and stripped of his medal because of a positive drug test. This leaves Bahrain with no Olympic medals at all, however Bahrain does have some athletes (all imported from other countries) who could potentially medal in athletics.
EUROPE - Albania, Andorra, Bosnia & Herzegovina, Cyprus, Malta, Monaco, Montenegro, and San Marino
Albania - Erkand Qerimaj is the current European champion in the 77kg class in men's weightlifting, and also heads the world rankings. Another potential medalist is Majlinda Kelmendi, a judoka who wanted to compete for Kosovo at the Olympics, but couldn't because of Kosovo's status. She has an Albanian passport, which she uses for convenience purposes, so the IOC suggested that she represent Albania instead.
NORTH AMERICA - Antigua & Barbuda, Aruba, Belize, British Virgin Islands, Cayman Islands, Dominica, El Salvador, Grenada, Guatemala, Honduras, Nicaragua, Saint Kitts & Nevis, Saint Lucia, and Saint Vincent & the Grenadines
Grenada - Should Kirani James qualify for London 2012, he will be Grenada's best chance ever to get its first Olympic medal. Kirani is the current world champion in the men's 400m in athletics.
OCEANIA - American Samoa, Cook Islands, Fiji, Guam, Kiribati, Marshall Islands, Micronesia, Nauru, Palau, Papua New Guinea, Samoa, Solomon Islands, Tuvalu, and Vanuatu
SOUTH AMERICA - Bolivia
With 18 Summer Olympic and 8 Winter Olympic appearances, Monaco holds the dubious distinction of having competed in the most Olympics without having an Olympic medal. With 160 million people, Bangladesh holds the dubious distinction of being the most populous country in the world without a single Olympic medal to its name.
Here are the countries that have won Olympic medals but will be coming to London in hopes of getting their FIRST Olympic gold medals:
AFRICA - Cote d'Ivoire, Djibouti, Eritrea, Ghana, Mauritius, Namibia, Niger, Senegal, Sudan, Tanzania, Togo, and Zambia
ASIA - Afghanistan, Iraq, Kuwait, Kyrgyzstan, Lebanon, Malaysia, Philippines, Qatar, Saudi Arabia, Singapore, Sri Lanka, Tajikistan, and Vietnam

OCEANIA - Tonga
SOUTH AMERICA - Guyana and Paraguay
The Philippines has the dubious distinction of winning the most medals without a gold medal, a record that was held by Mongolia until 2008, when Mongolia pocketed its first two Olympic titles.
This list will be updated leading up to the Games.
