My prediction will be 6-continent season on a westward route:
1-2 legs in Oceania
3-4 legs in Asia
2 legs in Africa
3 legs in Europe
1 leg in South America
Oceania
Australia, probably Melbourne and will visit first, having had recently visited in TAR Norge 1 and the city never visited in the original version. Qantas and United Airlines has flights to/from Los Angeles, only Qantas has direct flights between LA and Melbourne.
Asia
The Philippines (my country), hasn't visited since TAR5, but has been stapled on numerous visits in international versions as well, the recent is Velyki Perehony (the Ukrainian version of Race). Although the southern part of the country has an extreme caution of travel warning list, only the northern part of the country (specially the island of Luzon) is probably safe. Let's pray for Philippines on TAR24 visit. #PrayForPhilippines
South Korea. Last visited since TAR17, but only Gyeonggi Province and Seoul were visited. This time, Seoul will be have a full leg there, including Gangnam district, scouting to learn "Gangnam Style" dance.
Sri Lanka, same description; hasn't visited since TAR6, but has also recently visited in Velyki Perehony. Like the Philippines, it has stapled with numerous visits. Colombo never had a Pit Stop in the original version, the exact possibility for the Pit Stop is Negombo, a coastal city close to the international airport.
Africa
After post-UB, no more Malawi, Tanzania and Botswana...
Let's go to South Africa, last visited since TAR7 with only Jo'burg and Cape Town visited. Like the countries above, it will have a scenery view of safaris and wildlife.
And no other African countries in the Central part of the continent on the Atlantic coast (Angola, Benin, Cameroon, Gabon and Togo) will visit there, except two Congos.
Europe
Lots of European countries to visit: Albania, Andorra, Belarus, Bosnia and Herzegovina, Bulgaria, Cyprus, Latvia, Luxembourg, Macedonia, Malta, Moldova, Montenegro, Serbia, Slovakia and Slovenia. Only Bosnia and Herzegovina was recently visited in HaMerotz LaMillion 2. This is a possibility of the teams could race on a cold pre-winter snap in the months of November and December. Moldova could chance to have visit there and despite on being the poorest country in Europe. Finland could host a race there and never had a Pit Stop before.
And parts of Spain (not including Barcelona and Mallorca) will get a chance to race, probably including the capital city of Madrid.
Plus, no more (Metropolitan) France and Germanic countries (Austria, Germany and Switzerland).
South America
Brazil. Rio de Janeiro was recently visited in TAR18; and it will have to get racing months before next year's World Cup. There is a chance to visit Sao Paulo (the country's largest city) for the penultimate leg. Other Brazilian cities could have an option to visit: Belo Horizonte, Brasilia (the capital), Curitiba, Manaus, Natal, Porto Alegre and Recife.
